This is a remix of droftarts parametric pulley thing.
With this library, it is possible to create "[...] a range of metric and imperial tooth profile pulleys, with any number of teeth [...]" (droftarts). Use the CUSTOMIZER to generate your suiting pulley!
This remix just provides an improved CUSTOMIZER interface. Descriptions for the parameters are now also visible in the CUSTOMIZER interface and profiles, etc. are selectable via dropdown menues! All credit for the technical part goes to droftarts! For a couple of precompiled pulleys and furhter information, refer to the original thing.
Have fun creating your customized pulleys!
