Description

This is a custom PSU Case for the Mean Well LRS-350-24 to fit in the Prusa Full Bear Frame. It was designed to be flush and contour fit with the Bear Frame while also incorporating a rear mounted power plug.

The PSU Case is the only part that requires supports. I use Support Enforcers and only select the two overhangs with paint on supports. Example .3mf included.

It uses modified PSU Upper Mounts, and it works with the existing Bear PSU Lower Mount. The PSU Back Plate part is thin so just be mindful when pulling out the power plug.

Hardware Needed: Power switch, Power plug with power panic, 7 m3 square nuts, 1 m3 washer, 1 m3x12 SC, 4 m3x6 CS, 2 m3x12 CS, 3 m4x8 CS, 2 m4x8 PH.
