USB Charger 2020 (4020) mount

I had a PSU cover with a USB charger mount. I switched to a small PSU, so I “designed” this rectangle with 3 holes. Grab a USB car/marine charger from Amazon, AliExpress, or wherever to put in the big hole and M5 bolts with t-nuts in the small holes to anchor to the extrusion.Connect your charger to your PSU. The [charger I ordered](https://www.amazon.com/dp/B07NV9D61R) handles 12v-24v and displays the input voltage as a nice extra. Double-check your charger supports your printer's voltage. I used a charger with a USB-A (QC3) and a USB-C port. You can also find a variant with two USB-A ports. However, it only supplies 2A and the RPI claims to need 2.5A, while the RPI4 wants 3A. So, I might need to do some testing to use if this will actually work well for its purpose.Now you can power a Raspberry Pi, your phone, or something else from your printer.
