Production-quality mechanical STL files: spur gears, worm drives, living-hinge assemblies, threaded inserts, and precise engineering brackets. Verify thread pitch, gear module, and hole tolerances in the 3D viewer before printing.
Gears, Cams & Drives
Spur gears, bevel gears, worm drives, and rack-and-pinion sets — module and tooth count listed per file.
Verify Tolerances In-Browser
Use the measurement tool to check bore diameters, shaft clearances, and wall thickness before printing load-bearing parts.
Assembly & BOM Notes
Multi-part assemblies include parts lists, hardware specs, and print orientation instructions from the designer.
HiddenMark on Every File
Mechanical design downloads carry a unique watermark — engineers can trace any shared or resold file to the buyer.
0% Commission
Mechanical designers keep 100% of every sale. Proofly earns only a small buyer fee — never a creator commission.
