A bracket for attaching an ATX (regular ol' computer power supply) to 2020 extrusion, but please note, although I show it suspended in a vertical orientation with just this bracket, I wouldn't recommend it! This was designed, and is currently used, with an additional support below the supply. This bracket will support the weight of the supply by itself, but my concern is whether that would stay stable long term, after exposure to heat from the PSU.

Should print fine without supports, brims, etc.
