I wanted to have a bed-mounted camera on my Ender 5 S1, but all of the premade ones I found didn't fit in one way or another.

This should be compatible with any 2020 extrusion; I included holes in the side and bottom for locking it down with a t-nut if desired.

Here's a shorter version as well, in case you need more clearance like I ended up needing after I redesigned the M5-threaded mount for my C920.
