The Logitech POWERED is a wireless charger released in 2018. This works with the “Apple Watch Magnetic Charging Cable” USB-A version, the USB-C version is untested.

Instructions

Provided are the Fusion 360 source file, and print files for Original Prusa MINI+ and Prusament.

If printing from the STL, printing on the back with supports has worked well for me. Inspect the G-code to see in better detail if you are unsure.

Fitting the charger is a little tight, as it goes in at an angle. You just need a little force to snap it in place.

Slide the attachment over the top of the charger and you're done. Clean up the look with some 3d printed cable guides for extra points (not provided).
