Built it a year or so ago with my ender 3 pro. Been sitting in my cubby since then.
Needs minor improvements.
Works with my magsafe wireless charger and my mag safe cases.
The side cutout is for my usb hub I piped into there.
Tape residue on ball to add some friction as this print wasn't as tight for mounting.
Filament: https://amzn.to/4aquOSi Polymaker Matte PLA Army Blue.
Charger used: https://amzn.to/4a5b5I4 Out of stock currently.
Similar charger: https://amzn.to/43tUjQl Not sure if it matches the ball mount size.
USB mount in cubby: https://amzn.to/3TQkTQw USB Mount for cubby. Wouldn't recommend side mounting like I did.
