Mining Rig Brackets
thingiverse
The fan piece is made to fit snug on purpose so it doesn't slide down by itself, you will need to trim the elephants foot if your printer has that issue with prints. As for the psu brackets, one is made for the left side of the rig with fan from it pulling cold air from the side, same applies for the right side, the lower psu bracket is made for the psu with fan pointed upwards when it's laying flat, these are made for my rig specifically and could possibly fit for yours as well as they should be universal.
