It is a parametric pulley designed in OpenScad. I believe the Thingiverse
website allows you to configure openscad designs from the website, then
download the.stl. But you can also download the Openscad file.
.stl is what your slicer (CAM for 3d printers) wants.
For a reliable motor-mounted pulley, I ended up doing something similar to what
Chris Albertson describes. Mine was a plastic pulley with a hub that has two
pockets for clamp nuts. The OD of this hub fits snugly into a metal ring with a
pair of radial holes. The set screws run through these holes, thread into the
nuts, then bite into the motor shaft.
