CAD / STEP Files

Hello everyone,

I'm in the early stages of building a Foldarap. Bought my aluminum and laser cut some acrylic... I wanted to add a Raspberry Pi and an IP camera to my build so I could hopefully run the whole thing off of octoprint and do remote printing while not at home. My question would be, is there a CAD model for this build somewhere out there? I tried to import the STL files into Fusion 360 and convert them over to bodies, but it was very unsuccessful. I'd love a CAD model or even STEP files of all the printed parts so I could assemble something in Fusion. Thanks for your time!!!!!

Also any tips or words of warning would be welcome as well (building a 3d printer is all new to me).

The source file is a .sketchup format if you want to play with it
(but no step/iges files unfortunately)
