20T Spur Gear – Module 1 (m1) – High‑Precision Functional Gear for 3D Printing

This 20‑tooth spur gear (Module 1) is a professionally engineered component designed for functional mechanical applications, gearboxes, robotics, DIY mechanisms, and educational engineering models. The tooth profile is optimized for smooth meshing, low friction, and accurate power transmission, even when printed on standard FDM printers. This gear is ideal for: multi‑stage gear trains mechanical demonstrations renewable‑energy learning models The model includes STL for direct 3D printing and STEP for CAD modification or integration into your own assemblies. Main dimensions are included in the model for easy reference and integration into your own designs. Custom modifications are available upon request, and I can also extend this gear series with additional models if needed.
