Couldn't quite find the camera mount I wanted for my Ender 5, so I took an afternoon to design my own. Files are all in the correct orientation to maximize strength at the joints. The base of the unit clamps on with 4 M3x12mm screws with press in place M3 nuts on the underside. I probably could have gotten away with just two screws. The joints are secured by M3x19mm screws with press in place nuts. The angle is adjustable just like a gopro mount. I have included a 69 mm and 109 mm arm, if any other lengths would be useful, let me know. Prints well without supports in PLA.
WARNING: This print does not intersect the print volume, but the edge of the stock extruder of the Ender 5 will collide with the mount if you go all the way to the edge of the build volume and have set up the mount as pictured. Keep this in mind when slicing.
Additional Parts needed:
4 - M3x12mm screws
2 - M3x19mm screws
6 - M3 nuts
