I have begun printing parts out of PLA to dial in dimensions. I am hoping to have the final pieces printed out of ASA but I am known for using my prototype parts indefinitely until they fail. 

This is a good time to remind myself to double check the accuracy of any 3D models found on the internet. The 4 main mounting holes for the ender brackets are in the completely wrong place, and the pro micro model I found was too small. The Ender 3 has gone through so many micro revisions though so I can only blame myself for that one.

My wheel and pedals are expected to arrive in less than 24 hours. All I need to do is fit test everything with PLA before I go to bed, have the ASA prints run over night, and then code and wire the electronics tomorrow morning without anything going wrong.
