This takes Thorinair's C270 housing and merges it with Sneaks Pi Camera articulation system. Sneaks articulation system is solid, rigid, and all around offers some great flexibility to getting an angle that you like.
I have a X aluminum end-cap that I also modded: https://www.thingiverse.com/thing:4549749
I've printed this in PLA and ABS and both seem to be a little bit small for my disassembled C270. If you increase it 4-5% it will fit fine. The screws might not, but a little double sided tape for cushion and the tight clam trap that happens with the front lid gets put on make it snug as bug.
I included the focus ring but no mods have been done to it--it fit fine for me without needing to scale it.
Your mileage may vary.
I won't call this the best mod of my life and if you wish to do better I just slammed it around in tinkercad: https://www.tinkercad.com/things/hOBSN0PqlGy
It works though and I like it quite a bit.
Note: you will need the ball joint and the rest of the parts from the Pi articulation system.
