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.
Print-in-Place Flexible Crocodile
Toy reptiles are fine until you try to pose them and realise they're cast into a single, rigid block that snaps if you push it. This fixes that. It’s an eight-segment articulated crocodile that prints entirely assembled, right on the bed. The joints are enclosed captive hinges with a 0.45mm clearance, meaning they fuse just enough structure to print safely before breaking free instantly for a massive range of motion. The body tapers from a stylized head down to a narrowed tail, with distinct rib extensions and legs built into the mid-sections. Print Instructions Clearance: 0.45mm gaps in the hinges — make sure your flow rate is dialed in to avoid the joints fusing. Layer Height: 0.2mm recommended. The internal pin tapers rely on standard layer heights to bridge successfully. Adhesion: It prints flat. No brim is required unless you have severe warping issues on small footprints (like the tail tip). Supports: None. The hinge pins use 45-degree chamfers so they print perfectly in mid-air inside their sockets.
Lumina — MTB Forward Light Mount
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
Rim Bead Saddle Sanding Block
A custom sanding block cut with a compound saddle shape to finish the outer lip of a 20-inch rim. Primary Curve: Matches the 20-inch overall rim diameter. Secondary Groove: Sweeps a 15mm-radius profile along the main curve to cup the bead lip. Grip: Pinch grooves along the sides for better control while sanding.
Sentinel Backup Camera Pod
A rugged, underslung surveillance pod designed to give a powered wheelchair rear-view capabilities. The enclosure mounts flush against T-slot tracking, holding an ESP32-S3 and camera module securely out of the elements. Hardware Integration Board Mounts: Internal standoffs spaced for a standard ESP32-S3 DevKit, sized for M3 heat-set inserts. Rear Panel: Dedicated cutouts for power switch (11.5 x 8.5 mm) and a USB-C feed (12 x 6 mm). Camera: 6mm forward-facing aperture. Lid: 2mm flat plate secured by four M3 screws into corner bosses. Mounting: Twin M3 clearance holes in the base (the "top" when mounted) to bolt directly into T-slot nuts.
1:100 sailing Hull Boat Model
A scaled representation of a 40ft displacement hull vessel, configured with a 15ft beam and an overall 25ft height profile (including the flybridge/superstructure). The part is modeled at a 1:100 scale (1 foot = 3mm), resulting in a print envelope of exactly 120mm x 45mm x 75mm. Fitment Notes Hull Profile: Features a sharp forward entry transitioning into a flattened stern with hard chines, standard for planing speeds. Base Dimension: Check your bed clearance for the 120mm overall length. Orientation: Prints flat on the hull bottom (z=0). You may need supports for the angled windshield overhang depending on your printer's bridging capabilities.
Dwarven Rampart With Battle Scatter
A heavy tabletop defense rampart for 28mm-scale wargaming, featuring a wide walkway, solid rear stairs, and deep dwarven geometric cuts along the front. Remix Hooks Scale: The wall sits at a 120mm width and 30mm height — scale the overall block if you're fielding larger forces. Scatter: The walkway holds a small 12x10mm dropped chest and a plunged sword. You can freely translate these across the -Y and X axes, or replace them with your own fallen shields and banners. Details: The geometric diamond cuts on the front face are modular — swap the depth or pattern to match your specific underground factions.
Folding Scooter Backrest
Riding a mobility scooter without back support turns every bump into a spine test. This two-part folding frame bolts directly to a flat seatplate, giving you a sturdy backrest that folds flat out of the way when you need to load the scooter into a car trunk. The heavy-duty hinge locks against a stop block when upright to keep you supported. Specifications Seatplate Mount: 140mm x 100mm overall. Mounting Pattern: Four 8.5mm holes spaced 110mm x 70mm apart (fits M8 bolts). Backrest Dimensions: 220mm wide by 240mm tall. Hardware Required: One M8 bolt and locknut for the main hinge pin. Both parts are oriented flat for printing without supports. High infill recommended for the hinge knuckles.
PortaBend — Offset Elbow Plate
PortaBend is an offset mounting plate featuring an integrated 90-degree tube bend. It offsets a fluid or air line vertically before routing it horizontally at a 20-degree angle. The integrated barbed nozzle at the end holds standard tubing securely without requiring extra clamping elements. Features Offset integration positions the line clear of immediate obstructions. 20-degree angle built straight into the pipe body for awkward routing geometries. Internal bore runs flush from the underside directly out the horizontal pipe barb.
80-95mm to 66mm Can Adapter
A drop-in adapter sleeve designed to secure slim 500ml energy cans within oversized vehicle cup holders. Three exterior leaf-spring fins flex to accommodate base diameters ranging from 80mm to 95mm, centering the inner cup and dampening vibration to prevent rattling. The base features a tapered leading edge for binding-free insertion. Technical Specifications Inner Well: 66mm diameter, sized for standard 500ml slim cans. Outer Fitment: Expands to 97mm; compresses to fit 80mm–95mm automotive cup holders. Retention Mechanism: Three curved 1.2mm-thick leaf-spring fins. Recommended Material: PETG, ABS, or ASA for high-temperature resistance in vehicle interiors. Print Instructions: Prints upright without supports.
Drop-In Floyd Hardtail Block
This L-shaped blocker forces a Floyd Rose-style tremolo into a fixed "hardtail" state without permanent modifications. What it's for Instead of a simple wedge that can vibrate loose, this block drops into the gap between your sustain block and the cavity wall from the back of the guitar. The oversized flange catches on the wood surface, keeping it suspended right in the sweet spot so it won't ever slip down or fall out while playing. It's printed flat to align the print layers against the string tension, preventing delamination over time. Dimensions Width: 38mm (matches standard Floyd blocks) Gap thickness: 12mm Insertion depth: 28mm Flange hook: 8mm overhang Remix ideas Modify the gap_thickness to perfectly match your specific route and preferred bridge angle. Widen the block_width if your cavity allows for a wider brace. Adjust the drop_depth if you have a shallower tremolo cavity.
Walkable SPD-SL Cleat Cover
What it's for A slip-on protection cover designed for Shimano SPD-SL road cycling cleats. It prevents slipping on hard surfaces like wet cafe tiles while protecting the plastic cleats from premature wear off the bike. Features a deep, cross-hatched tread pattern on the sole for traction. An internal tapered lip locks the cover securely over the top edge of the cleat hardware. A solid rim surrounds the treads to prevent the edges from catching while walking. Dimensions Internal Layout: 75mm long by 55mm wide at the heel, matched to standard SPD-SL profiles. Side Walls: 3mm thick for lateral rigidity and protection. Base: 4mm thick solid sole, structured to accommodate 2.5mm deep tread grooves. Materials Printing this model in a flexible filament like TPU is strongly recommended. The flexibility allows the inner retaining lip to stretch over the cleat body during installation and removal, while the rubber-like material provides the necessary slip resistance. Remix ideas Adapt the internal cavity geometry and overall footprint to fit Look Keo or standard SPD cleat profiles. Replace the cross-hatched tread with aggressive horizontal lugs or a custom dot pattern. Add a small tether loop to the heel end to leash the covers together when stored in a cycling jersey pocket.
AeroBox — Tape-Mount Box Winglet
The AeroBox Winglet adds MotoGP-inspired aggressive styling and aerodynamic structure to your motorcycle fairings. Featuring a complete closed-loop "box" design, the upper and lower swept aerofoils stretch outward and tie seamlessly into a sleek outer endplate. Instead of a single large, rigid backplate, the winglet employs two distinct, flushed mounting pads perfectly suited for heavy-duty VHB double-sided tape. This split-pad setup is significantly easier to conform to the natural sweeping curves of your bike's fairings. Features Closed Loop Box Design: Bridges a dual-element upper and lower wing wing with an aerodynamic vertical endplate. True Sweep: The wings heavily taper and sweep towards the trailing rear edge. Dual VHB Pads: Split bases keep the part tightly adhered without relying on a completely flat body panel. Support-Free Printing: Designed to slice straight from the flat side base directly upwards. Print Settings Print on its side (the flat base directly touching the build plate). Use high infill and at least 3 perimeters to ensure decent stiffness and durability. Standard PLA works for testing fits, but PETG, ASA or ABS are highly recommended for actual outdoor and speed use.
Stage-Ready Tremolo Cavity Shield
Cast in the sleek, utilitarian shadow of early-2000s metal, this tremolo cavity shield is scaled to cover the Floyd Rose springs on a classic shred-machine like an ESP KH-303. Its smooth, rounded profile rests flush against the body to protect the routing, leaving out the string-pass slots of later covers for a completely blacked-out, stage-ready silhouette. Dimensions & Setup Footprint: 142mm × 86mm, typical for vintage and modern Floyd Rose routes. Thickness: 2.2mm, keeping it rigid enough to resist bowing. Mounting: Six countersunk holes situated securely along the borders. Tuning Note: Since precise screw placement can wander between production years, double-check your existing instrument's hole spacing before setting the final drive!
