Steel Sheet Holders with Seesaw Eject Top Parts for Prusa Box Angular Control Panel

I've been slowly building my Prusa Box and knew I wanted the under-enclosure sheet holder, but wanted the battle-tested seesaw eject button. Since I started building my box, the creators have released new control panel designs, and the “Angular Control Panel” really spoke to me. These parts have been shifted forward to allow mounting with the stock holes on the Prusa Box.
