Ikea Lack mount/box for 360W power supply (Prusa i3 Mk3 upgrade)

thingiverse

I've suffered multiple failures of the stock power supply for the Prusa MK3 when printing higher temperature plastics, so I decided to source my own and design my own mounting/safety arrangements. This is the result. The power supply is a generic Chinese 24V 15A power supply - e.g. "EAGWELL" or "Menzo" of approximately 115 x 55mm (there are many compatible supplies). A slot is provided for a power entry module like IEC-GS-1-100. You will also need to provide a 4A, slow-blow fuse. A cable clamp is provided for bringing 12AWG "zip" wire out of the supply with strain relief. Both of these are available from Amazon. M3 flat head screws and nuts (e.g. M3x8) are necessary to assemble the cable clamp, and M4x8 flat head screws are necessary to fix the supply to the box and bracket. #12 screws are then used to screw to a table leg and the table bottom. It is very secure and overbuilt - it noticeably stiffens that leg of the table. I have provided a small hole to access the LED and voltage setting-screw. I have covered this hole with a piece of scotch tape on my build.
