I found this Bed Mount for the Ender 3 series (https://www.thingiverse.com/thing:4733900) and wanted to make a case to attach a Raspberry Pi Camera Module V3 to take time lapses of my prints.

The connectors should fit with this set of modular mounting parts: https://www.thingiverse.com/thing:2194278/remixes

Let me know if you try it!
