Description
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.

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.
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.
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.

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

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.
