M18x2.5 Socket Cap & Nut
An M18 x 30 socket head cap screw with a matching hex nut, designed for direct 3D printing. The bolt features a standard 2.5mm coarse pitch and a 14mm hex drive recess in the head. It prints head-down to avoid overhang issues. Fitment Notes Thread: M18x2.5 (Coarse) Drive: 14mm Allen / Hex Key Nut Wrench Size: 27mm Clearance: 0.2mm on the nut threads for a tighter fit. Ensure your printer's flow rate and dimensional accuracy are well-calibrated, or the threads may bind.
1U Omada Split Rackmount
A 1U split rackmount designed to securely hold a TP-Link Omada ER605 Router and an OC200 Hardware Controller in a standard 19-inch rack. The mount is designed to fit onto most consumer 3D printer beds by splitting exactly down the middle. The two halves securely lock together via three jigsaw joints on the base plate, requiring no glue or external hardware for assembly. Features front cutouts sized precisely for the ER605 and OC200 Internal guide walls hold devices squarely in place Rear stops are dimensioned to position the front faces of the devices exactly flush with the rack plane Base ventilation slots reduce filament use and aid passive cooling
Universal Split-Peg Node
A cubic structural node featuring universal split-peg snap joints on all faces. Identical Connectors: The top, side, and bottom faces all share the exact same split-peg geometry for multidirectional building. Tuned Tolerances: A 0.2mm radial clearance on the snap bulge allows the pegs to flex inward and securely lock into the internal cavities. Solid Body: Cutouts have been removed to ensure the internal cavities do not intersect, preserving the structural integrity of the snap mechanism.
Slotted Plank Deck With Pipe
A wooden-style planked deck, built at 45mm wide and 100mm long. Features two longitudinal slots and an elevated side pipe resting on 2mm pads. The opposite edge includes a 3mm wall, all contained within the requested footprint. 45x100mm overall deck footprint 6mm side pipe mounted on spaced 2mm pads 3mm retaining wall opposite the pipe Twin longitudinal slots (2mm wide, 1mm deep, 6.5mm apart)
Pegboard Utility Knife Holder
A drop-in holder built for standard utility and carpet knives, mounting flush to small-pitch pegboards. A generous front thumb cutout makes retrieval quick, while the three-peg top row distributes the weight. Form & Fit Internal Clearance: Sized at 40x20mm internally to comfortably swallow standard sliding break-off blades. Board Specs: Engineered specifically for 12mm center-to-center grids with 4mm holes. Pegs are 3.6mm to provide an easy slip-fit. Drop Spacing: The lower stabilizing bumpers sit exactly 36mm (three 12mm increments) below the main hooks to align with the board's grid. Orientation: Best printed upright. The 45-degree angle on the hooks easily clears standard overhang rules without supports.
Round to Rectangular Duct Adapter
A heavy-duty transition duct adapter for shifting airflow smoothly from a round inlet to a rectangular port. Designed with a continuous linear loft and constant 3mm wall thickness to minimize turbulence. Round inlet: 250 mm inner diameter Rectangular outlet: 300 x 220 mm inner dimensions Total height: 200 mm (including 30 mm attachment collars on each end) Wall thickness: 3 mm
M3 Socket Head Diamond Knob
What it's for A compact thumbscrew knob designed to press-fit or glue onto the head of an M3 socket head cap screw. The closed top provides a clean finish while the heavy diamond knurling ensures excellent grip. Dimensions Overall Size: 12mm diameter × 8mm height Recess: 5.5mm diameter, 3mm deep (sized for an M3 socket head) Knurling: 35-degree pitched V-groove diamond hatch Print notes Print flat on its base. No supports are required. If the bolt head is slightly loose, a drop of CA glue in the recess will lock it in permanently.
Hinged Dragon Injection Mold
Pouring liquid plastics into split molds usually ends with the halves sliding out of alignment, ruining the cast and spilling hot material everywhere. This print-in-place clamshell mold fixes that by locking the halves together with a permanent hinge and alignment pegs, ensuring a perfect seal every time you close it. The internal cavity forms a smooth, undercut-free dragon shape, fed by a top-mounted injection funnel. Air vents run across the parting line to prevent bubbles from trapping in the wings or tail. Mold Specifications Closed Dimensions: 100mm wide x 70mm tall x 30mm thick. Cavity Size: Roughly 45mm x 55mm (scales cleanly). Clearance: 0.5mm on the hinge mechanism — ensure your extrusion multiplier is tuned so the cones don't fuse. Material: Print in PETG or ABS for thermal resistance if injecting warm wax or low-temp thermoplastics; TPU works brilliantly if you need a flexible mold to aggressively demold rigid casting resins.

Eldosa — Distribution Enclosure
An electrical distribution and breaker box built for modular wiring. It features dedicated routing channels running alongside a raised central mounting boss, keeping cables neatly separated from the active components. The box relies on a simple, robust knuckle hinge designed to take a piece of 1.75mm filament as the pin. Features Inputs & Outputs: Three large 16mm inputs on the left flank, and five 12mm output holes on the right. Internal Routing: Twin divider walls keep power runs clean and separated from the main breaker rail. Hinge Design: Alternating 24mm knuckles on the box and lid mate tightly. Slide a bit of standard 3D printer filament through the 2.4mm bore to link them together. Signage: Raised "ELDOSA" lettering on the top cover. Print notes Print both parts flat on the bed. No supports are needed for the box's side holes if your printer handles bridging well, though you can add them if you prefer perfectly round cutouts. Ensure your bottom layer isn't heavily squished, or you may need to ream out the hinge holes with a 2mm drill bit before inserting the filament pin.
135x110mm Quarter-Sheet Sanding Block
A handheld sanding block dimensioned specifically for quarter-sheet sandpaper (140x115mm). The 135x110mm base allows the paper to wrap over the front and back edges, where it is secured into lateral slots using two printed wedge clamps. The upper body features a sculpted dome with deep finger and thumb reliefs to reduce hand fatigue during extended use. Base dimensions: 135x110mm Paper compatibility: Standard quarter-sheet (140x115mm) Clamping mechanism: Dual friction-fit wedges Ergonomics: Sculpted palm dome with directional finger grooves
25mm Wand Soldering Station Stand
This unified bench stand secures a standard 25mm soldering wand and a 1-ounce flux tin. The 40-degree cradle angle positions the heating element directly over the forward sponge tray, keeping the benchtop clear of dripping solder and preventing the flux jar from tipping during use. Fitment & Dimensions Cradle Bore: 27mm internal diameter, designed exclusively for 25mm wand handles. Thicker handles will bind; narrower irons may not seat securely. Flux Cup: 43mm bore with a 25mm depth. Fits standard 40mm/1oz rosin tins with slip clearance. Measure the specific flux jar before printing—larger footprint containers will not fit. Cradle Length: 50mm open-rib support.
Turret-Profile Sharpie Plotter Chuck
A stepped, turret-profile chuck designed to adapt standard Sharpie markers for use in pen plotters expecting an 11mm tool. The lower section drops seamlessly into the machine's carriage, while the flared upper collar houses an 11.5mm bore tailored to the 11.3mm grip and 13mm shoulder of a standard marker. Design Details Compression Collar: A vertical flex slot allows the upper section to clamp firmly onto the pen body without warping the base. Zip-Tie Channel: A recessed groove in the collar provides a secure seat for a standard zip tie to cinch the mechanism closed. Internal Stop: An internal taper arrests the pen's shoulder, keeping the tip height consistent across tool changes. Tip Clearance: An 8.5mm lower bore ensures the marker tip passes through smoothly without clipping the adapter walls.
Channel — Micro U-Profile
A precision micro U-channel profile built to exact specifications. Designed as an inverted U-shape, it features consistent 2mm wall thickness throughout. Dimensions Width: 8 mm Total Depth: 6.5 mm (yielding a 2.5 mm internal channel) Total Height: 9.5 mm Wall Thickness: 2 mm on both verticals and the top span Print notes Prints easily in its current orientation with no supports required. A slight 0.2mm chamfer has been applied to the outer top edges to eliminate sharp corners.
OsteoHinge — Resettable Femur Simulator
This anatomical simulation bone is designed for realistic mechanical training and demonstrations. Modelled at a compact 200mm footprint to suit standard print beds, it features a functional, re-settable fracture mechanism built straight into the main shaft. The midshaft utilises an interlocking V-notch joint tailored for sudden directional failures. By threading elastic shock cord through the central internal channel and tying it off in the polar counterbores, the bone is tensioned. It rests firmly aligned and rigid until lateral force (a "push") hits the threshold, causing the V-notch to ramp open and cleanly hinge to simulate a fracture. Stopping the lateral pressure causes the elastic cord to snap the halves immediately back into the unmarred state. Assembly notes Hardware: Requires one length of 3-4mm elastic shock cord. Tie-down: Feed cord completely through the continuous central bore, stretch for the desired breaking tension, and secure via simple knots. Both ends feature counterbores specifically to hide the tie-offs. Scaling: Feel free to scale the assembly up uniformly to simulate a full adult male femur (~225%), but note you will require a correspondingly wider elastic band.
Brutalist Framing Outer Clamp
A monolithic, brutalist-inspired L-block designed to enforce exact ninety-degree angles on unruly lumber. Engineered specifically to cure the dreaded parallelogram effect in picture framing, this outer squaring jig cradles two boards firmly against its orthogonal walls while the glue sets. Design Notes: Oversized Clamp Cutouts: Generous 44mm slots on each arm easily accommodate standard bar clamps. Glue Relief Vertex: A central circular cutout ensures escaping squeeze-out never fuses the project to the jig. Rigging Anchor: A central tie-down hole offers a secondary strap point for complicated assemblies.
50mm Rounded 4-Hole L-Bracket
A custom L-bracket with a fully radiused profile at the end of each arm. Built to support structural corners, shelves, or custom frames. Arm Dimensions: 50mm length, 20mm width Thickness: 4mm Mounting: Four 5mm holes total (two per leg), spaced for alignment and balanced load distribution. Profile: Radiused ends to prevent snagging and improve visual clearance.
Piano Key Drill Index
Sweeping upward in a measured crescendo, this curved bit index arranges thirteen metric drill bits in an escalating semi-circle. Taking its silhouette from the staggered keys of a piano or the tiered architecture of a classical amphitheatre, the stepped block keeps each bit distinctly visible and accessible, transforming a standard workshop necessity into a sculptural display. Design Harmonics Measured progression: Accommodates thirteen metric sizes from 1.0mm to 7.0mm in 0.5mm increments. Clearance envelope: Each vertical shaft is oversized by 0.3mm, allowing bits to seat smoothly without rattling. Quick reference: Crisp, embossed numerical markings sit at the base of every tier for instant identification. The sweeping curve naturally fans the fluted steel outward, providing ample finger clearance when reaching for even the smallest diameters.
Heavy-Duty Strap Tension Lock
A heavy-duty tension lock (tri-glide slider) sized perfectly for standard 50mm (2-inch) nylon webbing. This single-piece buckle uses a reinforced and raised center bar to ensure high friction, keeping straps tightly locked under load. Key Features Perfect Fit: 51mm internal width to give thick duty straps just enough clearance. Aggressive Grip: Three raised cylindrical ridges span the center bar to bite into the woven nylon and prevent slow slipping. Heavy-Duty Walls: 6mm thick external walls and a 9mm tall command bar mean this won't snap under tension. No Support Required: Prints entirely flat on the build plate.

Brutalist Saddle Bench Anchor
Rising from the workbench like a brutalist saddle, this monolithic cloven block transforms a standard 20mm dog hole into a firm cradle for unpredictable geometries. The heavy, geometric V-cut cleft is engineered to catch and stabilize rolling stock—dowels, metal pipes, or turning components—locking them dead-center against clamping pressure. By sinking a steep peg below the benchline, the fixture acts as an immovable anvil for holding cylindrical parts during routing, carving, or sanding tasks. Fixture Geometry The Cleft: A 90-degree notch spans the entire 50mm crown, dropping deep into the block to maximize surface contact on cylinders. The Root: The 30mm anchor peg is tuned to a 19.8mm diameter and features a tapered tip, ensuring a smooth plunge into 20mm bench holes while allowing just enough clearance to prevent binding. Bed Orientation: Invert the block so the flat top face sits flush against the build plate, allowing the entire model to print completely support-free.
Banded-Spine Dust Adapter
A high-traction, banded transition piece engineered to bridge the gap between standard shop vacuums and precision power tools. Its ridged silhouette evokes a segmented mechanical spine, providing a rugged exterior grip while handling rigorous suction demands. The stepped-bore architecture utilizes a 31.5mm outer diameter to nest seamlessly inside a primary 32mm vacuum line, while the 25.5mm internal channel slides definitively over standard power tool exhaust ports. Engineered Flow Traits Clamp-Lock Ribs: Circumferential exterior spines deliver an aggressive mechanical hold for metal hose clamps, practically eliminating slippage under vibration. Arrestor Flange: An integrated mid-line collar acts as a physical backstop, ensuring both hose and tool seat to the strict designated depth. Continuous Draft: The straight internal channel bridges the differing equipment sizes without choking off the volumetric air flow.
