I used Freecad to create all of the mechanically accurate parts in this model. I tried an assembly branch, but they were too unstable/hard to use so I just exported the models to Blender and assembled them there. I modelled the plastic pieces in blender and printed and created the real printer.
All of the freecad files are located in the zip I placed on openbuilds:
Here are the renders of model created mostly in freecad:
Here are some Pictures of the printer fully built:
