Ender 3 PSU rear mount

thingiverse

A set of brackets to move PSU from the side to the rear of Ender 3. **Does not fit Pro or V2**. UPDATES: 1. Alternative version **2.0** to be mounted with M5 bolts screwed into tapped holes in openings of profiles. Check if you have those holes tapped already or want to do it. Otherwise use version **1.1** This mod works only together with high legs that rises printer up to make enough space to fit wide PSU, for example squash feet of my design: https://www.thingiverse.com/thing:4389922. With these there's enough space to keep the PSU silencer too.
