This mount combines camera holder and turtle fin in one. It is suitable for all common micro cams with 12mm lens, tested with Runcam Racer 2 (1.8mm/2.1mm) and Runcam Micro Sparrow V2. I choosed the same cam tilt like the original cam mount with 50°.
Just slip it onto the front standoffs. For max strength you can add a zip tie to the top plate, there is a small hole to secure the fin, but for me it is not necessary.
There is a small gab underneath the fin to secure a LED strip, I added a strip with 4-6 LEDs to the top plate.
Because of several demands I added the "Flam-Ingo"-Remix made by Holger L. (creator of the legendary Manaz Flip Dick: https://www.thingiverse.com/thing:3737941).

To get a good combination of stiffness and weight I added a custom support for interacting settings.
I drawad a cube all around the fin and used general settings with 2-3 perimeters und 5% infill. for interacting volumes I used 4-5 perimeters and 25% infill.
Put the front of this mount onto the printing bed for less supportmaterial.
