Ender 3 low vibration tool holder PSU mount.

thingiverse

This is a PSU top mount tools holder designed for most tools used on the Ender 3 printer. After installing new fans and stepper motor dampers, I found that my tools would rattle during prints, prompting me to find a solution. Since I wanted the tools close to the PSU but silent, this design seemed like the perfect answer. Note: This print may require some supports or a short bridging section on the bottom, both of which should work well.
