Parametric pulley

This is a pulley I designed for a project of mine. I made it parametric as I need a couple different pulleys. It is a work in project which will not be updated if it works for what I need.

Update 29 Dec 2022 - modified keyway position

FYI I am a total noob in OpenSCAD, this is my first project using this software or other code CAD software. Before I was using SketchUp and Tinkercad but I wanted to do something where I can easily change the parameters so here we are.

Hope you enjoy this and you can customize or use this however you like, let me know if there is something i need to change but I will most likely not do it unless it is a critical thing and I can do it.
