Mini Rack 4U size x 10in (254mm)

This is inspired by others but designed from scratch.

Objective was to make a frame to hold 5 x raspbery pi, two of which have 2.5in SSD storage and all powered by a POE switch.

I used 10in as a size since there are commercial mini racks of this size. This made it necessary to print the 2U panels in two pieces since it won't fit on the Prusa 3.5 I use. All other parts print in one piece albeit 1U has to be at a diagonal on the plate.

Assembled using :
M5 x 10 with Hex heads
M3 x 16 for fixing sides to horizontals
M2 x 6 for the two pieces of the 2U panels (glue is an alternative)
M2.5 x 6 for fixing the pi carriers to the 2U panel.

I have provided .step files so you can modify to meet your needs.
 

You need four horizontals, two uprights and two sides 

Update:

Now complete with sides and back panels
