Mechanical parts and technical components
Assemblies with threads, joints and fitted clearances. Every dimension is a parameter, and the parts stay in step when one changes.
ModelForkCable drag chain
Five identical separate drag-chain links, 15x10 mm inside and 20 mm long, snap-pinned at the sides and posed in a gentle curve, with a top bar and an open to…
ModelForkPlanetary gearbox
Single-stage planetary gearbox: sun gear, three planets on a pinned carrier, and an internal ring gear, with a 4.67:1 reduction when the ring is fixed and th…
ModelForkCorner hand crank winch
Corner-mounted hand-crank winch: an L-flanged frame with a chamfered mounting corner, two bearing cheeks, a flanged spool fixed to an axle, a crank arm, and…
ModelForkArchimedean screw
Single-piece Archimedean screw: 12 mm core with a right-hand rectangular flight (36 mm major, 18 mm pitch) and 8 mm smooth journals on both ends.
ModelForkJack saddle pad
Bottle jack saddle pad: 55 mm disc with a raised locating ring on top, a 28 mm piston boss underneath and four drain holes on a 36 mm bolt circle.
ModelForkBevel gear pair 90
Two meshing 90-degree bevel gears (16T and 32T, module 2) sharing a common apex at the origin, each with a 6 mm x 15 mm integral shaft stub.
ModelForkSpring and centering cup
A closed-and-ground compression spring that sits on the floor of a separate cup with a centering boss inside the coil.

Scissor-style spring clamp: two crossed jaw arms on a pivot pin, with a compression spring between the handles that pushes them apart and closes the jaws.
ModelForkFilament bag clip
Two-jaw filament-bag clip with interleaved hinge knuckles, a sealing rib and groove, and a separate 4 mm hinge pin.

Dry-box hygrometer bezel: 50 mm ring, 8 mm deep, for a 45 mm face, with a 2 mm gasket flange and a separate knurled retaining nut.
ModelForkCorner clamp
90° L-frame corner clamp, 80x80x20 with a 40 mm opening, a printed M10 screw through the jaw and a ball-swivel pad on the tip.
About Mechanical
These designs show what parametric CAD can do with real engineering: mating parts, moving joints and tolerances that hold when you resize.
Fork one to change a dimension, then download each part as STEP for your CAD tool or machine shop, or as STL to print.
