30 Amp Power Supply (PSU) Underslung mounting

thingiverse

Continuing on my quest for an IKEA Lack enclosure, I decided it would be better to mount the PSU outside of the printer enclosure to help keep it cool. There are several mounting solutions available but I wanted the terminal block to be covered up and the supply cable not to stick out sideways so I designed my own solution. The terminal cover end is a remix of http://www.thingiverse.com/thing:2149707 Anet A8 Replacement PSU Cover LH-360W by Sparkyman1. This design is good but I found the lugs that locate into the PSU vent slots were protruding too far, resulting in brittle materials (PLA) cracking when fitting and removing. I reduced the protrusion of these lugs, and added a set of mounting lugs to enable the supply to be screwed onto the bottom of the Lack table. It has also been enlarged for depth, allowing slight clearance between the surface and the power supply body to ease fit and removal, and to help cooling. The non-terminal end of the bracketry (the second piece) was scratch-designed and is intended to remain fitted permanently to the mounting surface. To remove the PSU for maintenance, simply undo the two wood-screws from the terminal cover end and slide the PSU out of the non-terminal end bracket. The mounting lugs are designed to accommodate countersunk 5mm diameter woodscrews. I recommend drilling a 2mm pilot hole into the bottom of the Lack table top. There are two versions of the switch cover, one with a hole for a cable entry and the other with a slot to slip over already pre-wired installations. Any comments are welcome, let me know.
