Ford AC Control Knob

I broke the original knob in my ford work van and just out of necessity built another, I hope this helps someone else.
if you do end up using this please let me know I would love to know it wasn't such a waste of time.
Also sorry its not quite finished I was new to 3D printing at the time and it worked so I never ended up fixing it.
if anyone has a request for modifications please let me know I would be happy to help.
