Parametric pulley - lots of tooth profiles

thingiverse

Create a range of custom metric and imperial pulleys with any number of teeth specified in an OpenSCAD file. Supported tooth profiles include MXL, 40 D.P., XL, L, T2.5, T5, T10, AT5, HTD 3mm, HTD 5mm, HTD 8mm, GT2 2mm, GT2 3mm, and GT2 5mm. Edit the pulley's fit, base, captive nut slot for the set screw, motor shaft diameter, height, and belt retainers. Attached STL files serve as reference pulleys for reprap-sized parts. The OpenSCAD file was initially created to generate square-toothed pulleys, but it has been updated with tooth profiles for improved linear motion. To use, download the OpenSCAD file or customize through the customizer (though limits apply). Print your perfect pulley and adjust printing speed if necessary to reduce blobs and stringing.
