Ender 3 Super Silent PSU mod

The purpose of the modification is to make the Ender 3 V1 printer as quiet as possible and to place all electronics in a well-ventilated area.

Ingredients :)

-M3 heated inserts (or optionally M4 screws)
-M5x8 screws
-M5 T nuts
-2x80mm fans (for example: Arctic Cooling P8 Silent)

-Skr Mini E3 v2 (Original Creality 4.4.x board has the same mounting holes!)

All elements can be printed without support.
