Ender 3 Power Supply Top Bracket
thingiverse
After printing and installing this power supply mount https://www.thingiverse.com/thing:3154216 I found the movement of the power supply on the mount (due to the movement of the hot end and bed shaking the frame) was sufficient to cause intermittent power resets. Then I found https://www.thingiverse.com/thing:3468297 -- I remixed it as a mirror image (sorry, the remix search seems broken, won't work with full URL, Thing ID, or any part of the name or designer's ID) added my own part to let the flat face of the second support grip the upper corner of the power supply. Now it doesn't move at all, restrained on three corners, and I think this has completely solve the problem of rebooting in mid-print.
