Flat Belt Pulley Creator

This thing generates pulleys for flat belts (and straps). You create any size pulley, with or without a hub, for belts of any size. You can have any number of belts Your pulley can have zero to four mounting screws, with or without nut traps. The axel hole can be any size. You can create wheels with flat belts for tires.

Thingiverse Customizer sometimes seems to refuse to run. (It probably takes a lot of computer resources to Customize files for everyone in the world.) A workaround is to download the OpenSCAD application and process the .scad file on your own machine. I have posted a brief guide. http://bit.ly/openscad-at-home

UPDATE 1 (August 17, 2018) Redesigned the bottom of the nut trap to provide a better fit for hex nuts.
