LRS350 Dual Power Supply Mount

thingiverse

A sturdy mount for two LRS350 Mean Well 1U power supplies with an IEC 320 power inlet. There's a lot of room for wiring access, and the supplies are staggered so that you can access both sets of terminals from the side without disassembly. Secured with two screws each, and an internal lip shelf to take the weight. Two holes for wires out with 12mm automotive wire cover shown. A 1U supply is about 30mm thick - this mount will NOT work for generic 50mm thick supplies. The Mean Well power supplies have legit regulatory markings and a three year factory warranty. That makes me a lot less worried about fire. I've burnt through two cheap supplies - no more. These supplies run about $40 on Amazon - roughly double the no-name versions, but definitely higher quality. https://www.meanwell.com/Upload/PDF/LRS-350/LRS-350-SPEC.PDF I run one supply dedicated to the heated bed and hot end, and the other for the MKS board, steppers, fans, and lights. Both supplies are rated 29 amps @12VDC but this way they're loafing - they'll last a long time. Print the cover, then drill and tap 3mm holes to match. Keeps curious fingers safe.
