The Marmotte prefers a “mini” size camera, which is 21 x 21 mm. The camera that comes with the Avatar has compatible screw holes, but is slightly smaller, at a size of 19 x 19 mm. The additional problem with a micro camera in the Marmotte frame is that camera cage obscures the camera view. One needs to 3D-print a couple of shims that pad the width and bring the camera forward a little bit so the view is not restricted.
To build it, you’ll need:
- 2 x 3D-printed shims based from my Thingiverse Walksnail Avatar Micro to Mini Camera Adapter model
- 8 x M2 screws (3mm length)
- 4 x M2 plastic nuts
