Hue Play under desk variable angle mount

My Hue Plays wouldn't stick to the curved back of my monitor, so I decided to mount them to the underside of my desk instead. As I didn't know at what angle they would look best, I designed a mount that would offer me to adapt their orientation continuously between horizontal and vertical.

Printed them on their side and with supports (cleanup was a bit tedious, so any tips on how to improve this are welcome).
