I just spent far too much of my life making these printable, between fixing mesh issues Slic3r whined about, rotating the objects, and trimming a bit off the arduino bracket that protruded below the Z plane. Thought I would share.

I uploaded all the individual edited files as well as a plate with all the attached components.

I'm starting a print now; I'm happy with how it sliced, so I'm hopeful this will actually work. I'm calling it a WIP until I get a good print out.

Cheers!
