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.
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
Stealth Pillion Cowl Cap
A sharp, faceted pillion cover that borrows heavily from the brutalist angles of modern stealth fighters. Designed to sit directly over a standard passenger seat rather than replacing it, this cap runs extremely low-profile to keep the tail looking clean when riding solo. Fastening Internal Anchors: Four distinct strap loops are tucked into the side margins of the hollow cavity. Routing: Run flat webbing (up to 25mm wide) side-to-side through the loops and directly underneath the seat pan. Fitment: Wide, generic clearances mean it acts as a floating cap, letting the straps pull it snug without needing latch-specific hardware.
Motorcycle Numberplate Spray Deflector/Mud Guard
That perfectly aligned stripe of wet road grime the rear tire slings exactly past the bottom edge of the plate and up the center of your jacket is miserable. Tail tidies look good, but they leave the dead center of the wheel completely unshielded. This is a wedge deflector that clips directly onto the bottom edge of the numberplate. It projects a downward-angled, 18mm shelf backwards toward the wheel, catching that specific arc of water and directing it back at the road. The ends are heavily swept to match the sharp lines of modern sport bikes like the Z-series. Fitment & Printing Slot Width: 3.0mm, deep enough (15mm) to swallow standard plates. Features an internal 0.4mm friction ridge to bite onto the plate. (If your plate is very thin stamped metal, add a strip of double-sided tape inside the channel). Deflection Range: 90mm wide to cover the tire's central spray path, with an 18mm rearward overhang. Print Orientation: Drop it flat on its front face in your slicer. The awning prints upwards at an angle, meaning the whole piece prints cleanly with zero supports. Material: PETG or ABS/ASA strongly recommended. PLA will warp from exhaust heat or summer sun.
1x6 Toothed Plate
A custom 1x6 building plate combining three 1x2 toothed sections into a single piece. Features a standard 8mm pitch and 3.2mm plate height. Includes 9 teeth arrayed along the front edge. Designed with a hollow underside and clutch cylinders for compatibility.
Lumina — MTB Forward Light Mount_v3
A rugged, modular mounting adapter designed to bridge the gap between mountain bike stems and 35mm lights. Built to sit perfectly flat on the build plate for maximum structural integrity. Features Clears 20mm tight-fit clamping areas Sets your lighting array exactly 50mm forward of the stem center Modular split-clamp design with recessed M4 hardware cavities Beefed-up clamp ears to handle rough terrain without splitting
30x15mm Scale Taped Cargo Bale
A miniature taped cargo bale, designed to drop straight into 1:10 or 1:24 scale RC roof racks and flatbeds. Measures exactly 30mm long, 15mm wide, and 15mm tall. The tape bands are modelled with a very shallow 0.3mm relief — enough to catch a wash or some dry brushing when you paint it, but shallow enough that it prints cleanly without fighting your nozzle. Sizing Footprint: 30 x 15 mm Height: 15 mm clearance required Mounting: Drops in; secure with scale bungee cords or double-sided tape.
Classic Fluted Cue Joint Protectors
These fluted joint protectors keep the delicate threads of a 5/16x14 piloted pool cue safe from dings and debris. The set includes a female cap for the butt pin and a male plug for the shaft insert. When off the cue, they screw directly into each other for tidy storage in your case. Fitment Notes Piloted Clearance: The butt protector features a recessed cavity designed to clear the collar on Schon and similar piloted joints. Storage Configuration: The thread profiles are tuned to interlock smoothly so the two halves stay together when not in use. Grip: Six smooth flutes around the perimeter give you plenty of leverage to seat them securely without binding.
Maverick Dash Phone Wedge
A low-profile dash wedge built to tuck securely behind the gauge cluster in a Ford Maverick. It sits low to stay out of the primary sightline, angling the phone back steeply for easy screen viewing while keeping it firmly trapped behind the 6mm front lip. Dimensions to tweak Slot width: The flat pocket is currently 14mm wide, which clears most phones in a standard case. Rear slope: The back face is pitched forward slightly (the top edge sits 12mm inward from the base) to clear the sloped cluster plastic. Overall height: Capped at 30mm max.
Cross-Braced Support Trestle
Flimsy diorama supports that rack and snap under the slightest weight are a constant annoyance. This is a rigid support trestle built to exact dimensions, using a crossed center brace to lock the vertical pillars against lateral shear. Specs & Fit Overall Height: 30 mm Pillars: 3×5 mm profile, spaced exactly 30 mm apart (center-to-center). Bracing: 3×2 mm diagonal cross-braces, centered perfectly between the front and back faces. Print Settings: Lay this flat on its back (the 5mm faces pointing up/down) for maximum strength and no supports.
Onewheel Trunk Cradle
A thirty-pound wheel rolling freely in the back of a moving car is a problem that solves itself by smashing your groceries. This cradle stops the board from tipping and sliding on every sharp turn. Footprint: 180mm wide by 160mm deep — fits cleanly on most printer beds. Fit: The 290mm curve holds XR and GT tires perfectly, and Pints will seat securely against the slopes. Anchors: Features four 5.5mm countersunk holes for bolting directly to a cargo floor or wood base, plus two side channels for hooking a standard bungee cord over the tire. Printing: Needs a decent amount of infill (15-20% minimum) to handle the board's weight. No supports required.
Onewheel Charger Port Plug
Mud, sand, and metallic dust have a habit of finding their way straight into the exposed charge port, packing it solid until the charger refuses to seat properly. This plug seals the port to stop the debris before it becomes a problem. Fit and Printing Insert Diameter: 15.3mm, designed to friction-fit a standard Onewheel XLR charge port. Alignment: Features a 2.5mm keyway rib to match the port's orientation slot. Removal: Includes an extended tab with a 3.5mm hole for a lanyard, making it easy to yank out even with gloves on. Material: Print this in TPU (flexible filament) for a watertight seal and best friction fit, though PETG will work if your printer's tolerances are dialed in.
M2 Slotted GO 3S Mount
Fixed-angle TPU sleeve for the standalone Insta360 GO 3S camera, geared for flat-top drone frames like the AOS series. The Fit: Holds the bare GO 3 / GO 3S camera unit only (not the Action Pod). The Mount: Slotted M2 tracks spanning 19mm to 27mm, meant to catch 20x20 or 25.5x25.5 top plate hardware. The Pitch: Locked at 25 degrees of up-tilt. Print in TPU. Do not try this in rigid plastics; you'll never get the camera seated.
