GM 20218853 Molding Clip
What it's for Replacement wide trim molding retaining clip for 1981–1987 Buick Regal 2-door models (including Limited and Grand National). Designed to replace GM part #20218853, it secures the vinyl top and side wide molding directly to the roof and side pillars. Dimensions Width: 44.5 mm (1.75 inches) Height: 23.2 mm (0.915 inches) Base Profile: 1.6 mm sheet thickness Assembly The clip slides sideways over the factory body weld studs, locking in place via the 15-degree center tang. The side wings feature stress-relief slits and 35-degree downward-angled locking barbs. These flex inward as the metal trim presses down, then snap outward into the rolled inner lip of the molding to maintain constant spring tension against the body. Must be printed in PETG, ASA, or ABS. Standard PLA will shatter under installation pressure or warp in the sun.
Snapping Front Reflector Clamp
A sturdy, support-free front reflector mount designed for an 11mm handlebar. The clamp prints vertically, keeping the layer lines parallel to the main body to allow the rear hinge to flex open without snapping during installation. Mounting: Friction fit for 11mm bars, secured with a 15mm M4 bolt Interface: Flat 25x35mm front plate for gluing a standard reflector Durability: The screw tabs are fused directly into the clamp body to prevent stress fractures Hardware: Recessed hex trap for a standard M4 nut allows one-tool tightening
powerbox modular
A sloped-console enclosure for a custom battery power box. The case features a sloped front panel for mounting a DSN-VC288 volt/amp meter and a generic battery level indicator, positioning them at an ergonomic viewing angle. Outputs: Four 14 mm barrel jacks on the front panel. Inputs: One 14 mm barrel jack and a 17×12 mm power switch cutout on the rear. Internals: A segregated 70×60 mm battery compartment with retaining walls. Assembly: Four M3 corner bosses meant for heat-set inserts, securing a drop-on top plate.
5/16x14 Cue Joint Protectors
A matched set of joint protectors for pool cues using the 5/16x14 piloted joint standard, heavily used by Schon and similar makers. Includes a female cap to protect the exposed butt pin, and a male plug to seal the shaft insert. Both feature fluted outside edges for easy threading and unthreading. Remix Hooks Cue Diameter: Default is 21.5mm OD. Thicker cues might want 22mm; older cues might sit closer to 21.2mm. Clearance: The female thread (butt protector) is oversized by 0.6mm, and the male pin undersized by 0.2mm to survive FDM printing tolerances. Dial these in depending on your printer's flow rate. Pilot Recess: The butt protector has a 13.5mm diameter x 3.5mm deep recess to clear a standard Schon pilot collar. Grip Profile: The 4mm semi-circle edge flutes can easily be swapped for a knurled mask or flat-cut hex sides.

Domed 10-Inch Kicker Grill
A heavy-duty 10-inch subwoofer grill featuring six interwoven 1/2-inch round bars. The bars rise into a central dome for maximum excursion clearance, with the outer bars plunging smoothly along a spherical radius to anchor seamlessly into the mounting ring. Clearance: High-arched dome design to prevent cone slap on high-excursion 10-inch drivers like Kickers. Mounting: Standard 8-hole pattern on a 246mm (9-11/16") bolt circle. Hardware: Counterbored mounting holes accept standard socket-head cap screws flush with the face. Printability: Modelled completely face-down so the intricate bar crossings print flat against the glass with zero supports required.
60mm Functional Open Differential
A complete 60mm mechanical open differential and display stand. It separates the internal components—four spider gears on a central cross, two side gears, and a carrier housing—exactly as they sit in a full-scale axle. The carrier housing splits cleanly in half to accept the cross and side gears, bolting together to secure the assembly. Three hex-driven input and output axles press-fit into the gears, allowing you to turn the pinion by hand and watch the side gears rotate independently through the spider gear array. Assembly Notes Hardware: Requires four standard M3 screws to clamp the carrier halves together. The lower carrier is sized for self-tapping, while the top has clearance holes and countersinks. Gears: The bevel gears are toleranced for FDM with an 0.4mm nozzle. Press the three hex axles into the pinion and the two side gears. Stand: The entire assembled carrier and pinion assembly drops into the U-slots on the display stand. No glue required.

47x42x50mm Robot Arm Base
A simple 5-sided enclosure acting as the first axis base for a robotic hand. The box provides a sturdy foundation with 2.5mm walls and a chamfered exterior. Outer Dimensions: 47mm (X) × 42mm (Y) × 50mm (Z) Wall Thickness: 2.5mm on all closed sides Configuration: Open on the top face for inserting motors or wiring Features: 1mm external chamfers for printability and handling comfort
10-Inch Kicker Subwoofer Spacer 4800 ribs
A precise 6mm-thick mounting spacer for a 10-inch Kicker subwoofer, designed to match the 47KBRW10 frame. Features Bolt Pattern: 8 holes starting at the 11:30 position and distributed uniformly clockwise around the 252mm BCD. Cable Routing: Four dedicated horizontal underside rib channels. Fitment: Engineered with accurate 1-inch offsets for structural routing to avoid pinching or sealing issues along specific axes.
Apache 4800 Kicker Sub Spacer
A custom 6mm spacer for mounting a Kicker 10-inch subwoofer frame inside an Apache 4800 hard case. Features specific underside relief channels on the top and bottom edges (holes 1-2 and 5-6) so the case lid ribs can slot directly underneath without interfering with the mounting face. The top surface remains perfectly flat to ensure a flush seal with the speaker basket. Pattern: Standard 8-hole (252mm BCD) Clearance: 3.2mm wide by 3mm deep horizontal channels on Z=0 Thickness: 6mm overall
MoogMatch — Vertical 6HP Pod
A 6HP Eurorack extension pod designed to match the 20-degree panel slope of the Moog Mother-32, but modified with straight vertical front and back walls to eliminate printing overhangs. Features Perfect Pitch: Maintains the exact 20° slope of the Moog tier system. Support-Free: Vertical exterior walls drop straight to the desk, meaning this prints flat in one go. Integrated Rails: Features 2.5mm continuous slots built right into the lip for standard M3 self-tapping screws.
Sloped Power Box Enclosure v2
A sloped-console enclosure for a custom battery power box. The case features a sloped front panel for mounting a DSN-VC288 volt/amp meter and a generic battery level indicator, positioning them at an ergonomic viewing angle. Outputs: Four 14 mm barrel jacks on the front panel. Inputs: One 14 mm barrel jack and a 17×12 mm power switch cutout on the rear. Internals: A segregated 70×60 mm battery compartment with retaining walls. Assembly: Four M3 corner bosses meant for heat-set inserts, securing a drop-on top plate.
110mm Kayak Track Anchor Cleat
A heavy-duty 110mm zig-zag anchor cleat designed specifically for marine T-track systems. This assembly provides a secure tie-off point for 550 and 220 paracord, locked down with printed M8 hardware. Fitment Details Track Slot: The 8.5mm bottom alignment boss drops perfectly into standard 9mm (3/8") kayak track top slots without binding. Cleating: 5 staggered teeth with a tight base gap designed to wedge and hold tension on standard cordage. Hardware: Fully solid M8 threaded T-bolts (11.5mm x 22mm heads) paired with 25mm knurled hand nuts, spaced at 80mm to spin freely alongside the main cleat body. Customization: Features "Many Prints" and "JM" deeply engraved into the outer walls.

Kayak Track Anchor Cleat
A heavy-duty zig-zag anchor cleat designed specifically for marine T-track systems (YakAttack, Scotty, RAM). This printed assembly includes the cleat body, two M8 threaded T-bolts, and two knurled hand nuts. Fitment Details Track Slot: The alignment boss on the bottom of the cleat is sized at 8.5mm to drop perfectly into standard 9mm (3/8") kayak track top slots. T-Bolt Heads: The included bolts have 11.5mm x 22mm heads designed to slide through the wider internal channel of the track without pulling through the top. Hardware: The printed hardware uses standard M8x1.25 threads. The heavier 8mm shaft is vastly stronger than 1/4-20 when 3D printed, while still fitting flawlessly through a standard kayak track slot.
Stylized Mid-Century Sedan
A blocky, stylized tribute to mid-century automotive design, featuring a prominent toothy grille, rear pontoon fender bulges, and a sweeping roofline. Designed as a chunky, solid desktop toy rather than a scale replica. Assembly Notes Print-in-Place Capable: The wheels are currently modeled fused to the wheel wells for simplicity as a static model. Details: Includes raised headlights, bumpers, and the iconic vertical grille teeth. Scaling: Modeled at roughly 120mm long, making it a comfortable handful. Scale up for easier detail resolution on the grille.
Dyson V11 Car Crevice Tool
A long, narrow crevice attachment designed to fit Dyson V11 vacuums (35mm wand mount with a spring-clip catch slot). Built specifically to reach deep into car seat gaps where standard attachments cannot fit. The overall length is 220mm, transitioning from a round mount to a thin rectangular shaft, and tapering sharply at the tip to wedge into tight cracks. Remixing and Variables This model is built as a baseline for custom detailing attachments. Key dimensions to adjust for your specific needs: Shaft Reach: The main rectangular body is currently 160mm long. Extending this allows deeper reach, though printing vertically may require slower speeds or a brim. Tip Profile: The final 20mm tapers down to a 5mm outer width. Widening this slightly will improve airflow if suction is restricted; narrowing it further will access tighter rail gaps. Mount Clearances: The adapter sleeve has a 35.5mm inner diameter over a 25mm depth to slide over the 35mm wand. Adjust this clearance if your printer's bridging or shrinkage binds the fit.
Runner with larger studs and less protruding slope
A Lego-compatible replacement runner for a wagon door, redesigned for FDM printing. The geometry includes a solid sliding wedge and a 1x6 plate body. Tuning for Fit Printers often under-extrude small outer diameters and over-extrude inner channels. This remix tweaks the classic dimensions slightly to ensure good clutch power: Top studs: Bumped to 4.9mm. Bottom channel: Tightened to 4.8mm. Bottom pins: Increased to 3.2mm diameter to pinch the studs properly. Adjust these values if your printer needs more clearance.
Kawasaki M12x1.25 Skirted Mirror Cap
Threaded blanking cap for M12x1.25 motorcycle mirror mounts, designed to seal the exposed mounting boss after switching to bar-end mirrors. The flat, beveled head deflects weather, while the outer lip drops down over the factory hardware to stop water getting underneath. Fitment and Specifications Thread Standard: M12x1.25 fine pitch. Critical Check: Verify the factory bore diameter on the motorcycle. While this model is cut for M12, a significant number of Kawasaki factory mounts use M10 threads. Clearance: The 3mm deep weather skirt has an 18.5mm internal diameter, providing 0.25mm of radial clearance over a standard 18mm factory boss. Known Incompatibilities: Yamaha and certain right-hand Kawasaki mounts use a reverse (left-hand) thread. If the printed cap refuses to thread into the right side, mirror the geometry in the slicer or remix to reverse the thread direction.

13mm Reflector P-Clip Mount
What it's for A single-piece P-clip mount designed to secure a front-facing reflector to a 13 mm bicycle handlebar. It clamps entirely using the reflector's own mounting screw and trapped nut, keeping the profile clean. Dimensions Bar clamp: 13.4 mm internal diameter (allows 0.4 mm clearance for a snug fit). Reflector socket: 10.4 mm diameter, 4.0 mm deep. Nut pocket: 8.5 mm hex, 3.5 mm deep, sized for a standard M4 nut. Screw clearance: 4.5 mm bore. Print notes For maximum strength and flexibility when snapping over the bar, lay the mount flat on its side (Y-face) in your slicer. Printing in PETG is recommended to allow the hinge arms to flex without snapping along layer lines.

V-Drums Tripod-mount Rack Clamp
A custom-fit clamp for 1.5" Roland V-Drums rack tubes that provides a standard 1/4"-20 tripod mounting point. Designed to hold cameras, field recorders, or metronomes directly on your drum hardware. Features: Specifically sized for 38.5mm electronic drum rack tubes Captive hex pocket for a 1/4"-20 tripod bolt on the inside curve (bolt won't spin once clamped) Uses two M6x35mm bolts and nuts for the main clamp tension Prints flat with no supports needed
Terraced House Front and Sides
There's nothing more frustrating than having a beautifully detailed model building facade that leaves the sides looking raw when butt-jointed against another element. I've rebuilt this frontage to include matching brickwork side walls, giving you the extra pieces you need to finish the edges properly. Build Details Scale: OO Gauge (4mm to 1ft) Dimensions: Main frontage 64×72mm, side walls 10×72mm Assembly: Side walls print flat separately and glue to the main facade edges.
Terraced House Front with Quoins
Naked corners on a model building always look unfinished and make it impossible to hide the seam when you butt it up against a side wall. I've added alternating quoin stones up both edges that wrap the full thickness of the part to cap it off. Build Details Scale: OO Gauge (4mm to 1ft) Dimensions: 64mm wide × 72mm high × 3mm wall depth. Fit: Quoins extend back to the Z=0 plane and overhang the sides by 0.2mm to overlap any adjacent pieces nicely.
Absolute Zero Rocket Engine
Standard rocket bells have a nasty habit of melting into slag the second you hit full throttle, while the exhaust plume tears itself apart on the lower lip. This engine solves the heat. The upper combustion chamber is wrapped in a heavy cryogenic manifold system built to flash-freeze the core down to absolute zero, keeping the walls intact. Down at the base, rings of micro-vents bleed off the boundary layer to stabilize the exhaust plume before it exits. Footprint: 70mm diameter at the widest point of the bell. Height: 101mm tall overall. Mounting: Features a flat 44mm top collar, ready to fuse or glue to your fuselage. Printing: Generates upright as a single piece. The wide bell base acts as its own platform, so you shouldn't need supports for the main curve.
Burrito de Calibración Ajustado
Un problema típico de los modelos de calibración es que las proporciones no siempre evalúan bien lo que se busca. Un cuerpo demasiado macizo oculta defectos que una cabeza grande podría revelar. Este ajuste reduce el volumen central, dejando la cabeza como la masa principal. Dimensiones de prueba Cuerpo central: 12x16 mm Altura de inicio de cola: 9 mm Espacio entre patas: Reducido para puentes más cortos
