Description
Rebite de pressão (snap-fit) projetado especificamente para união de chapas finas, otimizado para impressão 3D em PLA.
O design foi ajustado para resistir às tensões da impressão FDM com bico de 0.4 mm. O rasgo central desce além da cabeça da trava, dando 3.0 mm completos de alavanca para as abas (que têm 0.65 mm de parede) fletirem sem estourar. A base da cabeça leva um pequeno chanfro de 0.3 mm para compensar o pé de elefante da primeira camada e garantir que ele assente perfeitamente plano contra o painel. A face de retenção tem uma inclinação suave de 80 graus para tracionar levemente o conjunto de 5.40 mm.

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.
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.
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.
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.

A solid, heavy-duty wall-mountable rack designed to hold five large screwdrivers vertically. Built to maintain a sturdy grip on hefty tool handles while keeping the mounting hardware completely separate from the tool shafts. Features: Accommodates 5 screwdrivers Wide handle cups (28mm) for heavy-duty tools Generous clearance between tool sockets and mounting holes Chamfered front and edges for a clean look Counterbored mounting holes for standard wood screws

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
