The frame that goes with the Runcam Micro and Runcam Split pods i have on Thingiverse.

Recess in the centerplate for extra rigidity

Suitable for mounting both 20x20 hardware and 30.5x30.5mm hardware

Ultralight frame for light fast builds

Reduced drag on the arm for higher top-speed and less propwash

Motorsize 1806-2306 16x16 or 16x19 layout

Note: you might need other m3 or even m2 bolts depending on your setup, m3 rubber vibration dampers also work great with this design
