Upgraded my workbench power supply with a 3D printed enclosure.

The completed upgrade. I regularly use barrel plugs and XT60 connectors so I added those along with the original banana plug terminals. Blue light is standby, the PSU is on. Red is active, fan kicks on and power is supplied.

The original monstrosity. I built this a year ago. It's ugly but it worked...except for the somewhat faulty button.

I followed the tutorial from dronebotworkshop.com.

I modeled it in Fusion 360 and printed 2 test fits. One hole had to be resized and one needed a redesign. Also, the gap around the switch was a bit larger than I liked so I tightened it up. It was well worth the 1.5 hours on the printer to ensure a good fit for everything.

I bolted the new enclosure to the computer PSU in 5 places. It ain't going nowhere! I was careful to keep the grill open so it could dissipate any heat generated by the power resistor.

It's pretty stout. The walls, top and bottom are 5mm thick. Printed with 4 perimeters, at 50% infill and 0.2mm layer height on a Prusa Mini+.

The base took 25 hours to print and the lid took 7.5 hours. The top layer on the lid was a bit disappointing. I need to fine-tune my profile for Overture PLA. Suggestions are welcome.

Tested and done! I'm super happy with this.

It's hard for me to work on tools because I'm too busy building stuff with them. But I'm glad I took time to make this happen. I expect it to serve me well for many years.
