I purchased this power supply: ABI 24V 500W Power Supply Indoor Outdoor LED Driver Rainproof Weatherproof 21A
I wanted a terminal cover with a power plug, on/off switch, and 3 XT60 connectors. I didn't find one on Thingiverse for this PSU, so i designed one in Fusion 360.
I used this socket: HONGYETAJA Inlet Male Power Socket with Fuse Switch 10A 250V 3 Pin IEC320 C14
Fusion file is below. You should be able to view and download.
- Prusa I3 MK3.
- AMZ3D PLA - neon-yellow.
- 0.3mm Layer height.
- Three top and bottom layers.
- Three perimeter lines.
- No supports.
- 25% infill.
- 210c nozzle and 60c bed.
I used 16 gauge wire on the XT60 connectors, since they could carry up to 24 amps of current. I soldered the wires on to the sockets, and added heat-shrink, before gluing them to the cover.
The photos show 24 gauge wire on the 120V side of the socket. I should have used a thicker wire, like 18 or 16.
I used Gorilla Glue to set the XT60 connectors and the socket to the PLA. I tried super glue, but it just broke after a few insertions/removals. The Gorilla glue is an expanding glue, so only use a little. I used a hobby knife to scrape the excess glue, before it fully hardened.
On the power supply, remove the 4 screws that hold the metal plate over the terminal strip. Remove the plate. Put the cover over the end of the supply, and use the same 4 screws to attach them together.
- I should have used thicker gauge wire on the 120V side. 18 or 16 AWG wire would be better. Those short lengths of wire should be able to handle 4 amps, but the electronic technician in me says "better safe than smoked".
- Perhaps the socket should have been rotated 180 - putting the switch on the outside, and the C14 plug on the inside.
I used beefinator's Cover Plate for inspiration, and to get the dimensions of the XT60 hole.
