Twin Cube Frame and Case for Framework Mainboard (version 1)

This is a take on Jay Doscher's Cube Frame for ITX, a modular server rack. Twin cube design was used to accomodate for Framework's rectangular profile. Everything can be printed without support, and put together using M2.5 screws (you'll need a lot).

The build comes in two main parts: the Twin Cube Frame and CPU Case. 

Twin Cube Frame is built by printing 8 side frames, 1 back frames, and connecting them together using the braces. Finally, attach the 4 cpu brackets to hold two CPU Cases in place.

CPU Case is built using 2 CPU Frame, attaching the mainboard using 10mm standoff, and connecting the CPU Frame together using 24mm standoff. You'll need to attach the rails for easier entry into the Twin Cube Frame. 

Optionally, you can attach the “CPU spacer” to top and botttom of the CPU Frame and handle to create a “portable” version of the frame. I'd recommend attaching some protection on the side by screwing on some perforated plates.
 

Finally, I'd like to acknowledge ManelTo's wonderful mainboard drawing which helped build the CPU Frame (the assembly reference file uses the stl). Please visit Jay Doscher's Cube Frame site, which inspired this model.

I've significantly redesigned the frame to use only single part for sides, as well as modify the back design to use 90 degree bracket instead of 3 way bracket of the original. The side panel was reused for Framework mainboard case instead of using the original ITX case.
