Ears and a back brace for a Mellanox SX6012. I used M6-1.0 x 30mm to secure it to the rack because the 3D printed bracket is a bit thick. I used #4-40 x 1/2" screws for holding the switch in.

I uploaded the Solidworks files, in addition to STL files. The ears are identical on each side, so you can print it twice, then you print 2 rear ear mount, and a back middle support to go between them. This gives you the bar in the back. Then the back_brace goes from the back mounting holes in the switch into the back supports.

Each part was printed with 3 wall layers.
