Summary

This nano camera mount is designed for 25mm x 25mm toothpick type quadcopters and relies on the flexibility of TPU to create a 'rollcage' type shape to hold & protect the camera, hence I've called it the Rollkage.

There are 5 variants for different length 14mm wide nano FPV cameras, the length in question is between the axis of the mount point to the very front of the lens (see the illustration picture).

Here's a few length examples:
14mm - RunCam Nano HD
12mm - Foxeer DigiSight V2
11mm - RunCam Racer Nano
10mm - RunCam Nano 2

Requirements:
Toothpick type quadcopter with 25x25mm flight controller mount setup.
Mount bolts long enough to protude 8mm beyond the top board, too short and the camera mount won't hold well enough.
Two M2x4 bolts to hold the camera on the mount.

There's also an optional 0.6mm thick TPU protector plate to print to try and prevent the camera touching the board immediately underneath it in a very hard crash, it has cut-outs to allow airflow over the flight controller or VTX below it.

Print in TPU, 0.2mm layer height, no support required. I specifically designed it to be a very easy print, meaning most printers should have no problems with it. Print only takes about half an hour.

Installation (see photos also):
1) Start by screwing the back strut of the mount down onto the quadcopter's flight controller mount bolts.
2) Then the screw down the front strut to create the main curve. It's very important that it's the right way up when installed (the same orientation as it was printed) if it's upside down the camera's lens will protrude out of the mount and have reduced protection.
3) Now install the camera by first installing an M2x4 bolt through the front camera strut and then through the rear camera strut on one side.
4) Screw that into the camera and repeat the process for the other side.
5) Now screw down the side struts of the mount on the main bolts.
6) Lastly tighten things up, the nature of the flexible design means the camera can be tilted/twisted slightly, giving it a bit of a forceful twist usually straightens things up.

Note that I have not been able to test this mount in flight yet due to being ill for the past 3 weeks. You're on your own for now! :)
