A 20-tooth, module 1 spur gear with true involute teeth, made with the Playground's built-in gear generator in one command (/gear spur 1 20 5). 5 mm thick, no center bore.
Key dimensions: pitch diameter 20 mm, outside diameter 22 mm, root diameter 17.5 mm, whole depth 2.25 mm, pressure angle 20 degrees. It meshes with any module 1, 20 degree gear. Print flat on the bed. Add your own bore after printing or in your slicer/CAD if you need a shaft hole.
Honest status: the exported mesh was read and checked (closed and consistently wound once 70 zero-area triangles are ignored). It has not been strength-tested or printed. The model was created with AI assistance.

Full Playground command recipe. Paste into the TrueGeometry Playground chat box. The gear command takes module, number of teeth and thickness in mm, so change those three numbers for any other spur gear.
