A mount for FPV micro cams (19mm) to put on 30x30mm stacks. Should keep most lenses completely protected, at least that's the case for the Micro Eagle I'm using it with.
Broke my regular 4" frame and had a RFX160 lying around that I didn't use because the way the camera is mounted is horribly fiddly, bloated and fragile. Printed this instead and now it looks super clean and tight, and while I haven't had any huge crashes I have crashed a dozen times with this and it's pristine so far.
Uploaded the OpenSCAD file as well if anyone wants to adjust due to tolerances or what-have-you. :)

Really easy and quick print, about an hour and I have my printer set pretty slow. These settings are what I used, anything should work, but if you print it with thin walls and no infill it'll obviously be flimsy.
