ATX PSU Bracket

Another design for my PC-in-a-Desk project. This is just a bracket to cover a hole I'll cut in the box and hold the PSU in place. I've kept it extremely simple because I don't know yet what way I'll orient the PSU. It may be on the floor with the fan pointing up or it may sit on its side. In view of this I made a vertical bracket for the back end and there are horizontal brackets on Thingiverse already.

After printing this and taking the photo on here, I realised my plywood is 12mm, not 9mm so I tweaked the design after that photograph but before uploading the STL.
