PSU Holder with fan for Prusa MK3 Ikea Lack Enclosure

The PSU of my MK3 pinter used to become very hot, very quickly when printing.While building the IKEA Lack enclosure from https://www.prusaprinters.org/cheap-simple-3d-printer-enclosure I decided to do a slightly different and activly cooling PSU holder. This is the first outcome. Please be aware that there is a left and a right hand mounting (prusa original mount is right hand). The air outlet is different for the left hand one. For me, the cooling with a low rpm fan worked better when left hand mounted. The Holder is attached to the Lack with 2 6x30mm screws.To attach a fan you can use M3x30I currently have https://www.bequiet.com/en/casefans/266 attached, because of the "Rubberized fan frame for less vibration" :-)
