Power Supply cover for 24V->USB for Raspberry Pi. Ender 3 Mount

thingiverse

This part is an enclosure for the KIS3R33S 24V to 5V USB power converter to power a Raspberry Pi (in my case a 3B+). It encloses the power module and attaches to the side of the Ender 3 power supply. You will need: 3x M2x20mm 1x M3x6 1x M4x6 1x KIS3R33S power module Mounting Instructions: 1) Remove the Power supply off the Ender 3. 2) open black AC cover (2 M4 bolts) and expose the contacts. Add 24V wires off spade terminals and thread through the black AC housing (see photo). 4) replace black cover and tighten up 5) Remove side screw (M3) to mount the case (this Thing) 6) Mount the base of this Thing using M4x6 and M3x6 bolts 7) position ki53R33S on base and measure wires. Cut wires and screw into terminals of KIS3R33S 8) Place M2 screws into Lid and get the screws to be slightly proud of case (extruding through holes) 9) Place KIS3R33S PCB onto lid and then flip over and screw into base Please note that the M3 screws tap into the base. Course threaded bolts or self-tappers might work better but this is what I had to hand.
