Hinged Dragon Injection Mold
Created today
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.
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.
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.
Narrow Dyson V11 Crevice Tool
A specialized extension nozzle designed for reaching deep into narrow spaces, such as car seat gaps and tight tracks. The base features a 35.5mm inner diameter sleeve tailored to fit over a 35mm Dyson V11 wand collar, providing a secure friction fit over a 25mm depth to clear standard spring-clip catches. The main body flattens out, while the final 20mm tapers sharply into a thin slot for maximum penetration into cramped areas. Mounting interface: 35.5mm ID, 25mm deep sleeve intended for Dyson V11 mounts. Nozzle profile: Flattens along the shaft, tapering to a highly restricted slot at the tip. Target application: Automotive interior detailing and reaching confined household crevices.

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.
