6 inch 4 post rack V2

This is version 2 of the 6 inch 4 post rack. The original one relied on glue, but this time around, just screws. Another improvement made was the depth. This should allow for 120 mm fan on the sides (adapter will come in a little bit).

There's a V3 (Which isn't compatable) here: https://www.thingiverse.com/thing:2870459
