## Comments
You may need to update the inner body design if motors are too long. My Nema-17-like motors dimensions are: 42x42x33
If you no need the inner body, then maximum motor height depends on shaft size

## Optional parts
* 1x-inner-body-top (RPI FPV)
* 1x-inner-body-bottom (RPI FPV)
* 2x-inner-body-opposite (RPI FPV)
* 1x-top-frame (Jetson Nano, has mistakes)
