Summary

3 inch drone frame.

I printed it in Polycarbonate.
The arms are 5mm thick maybe a little overkill but better save then sorry.

The FC mounting holes are 25.5 mm
The camera size is 14mm
The motor has a 9 x 9mm mounting pattern

Everything is mounted with 3mm bolds.

Everything can be printed without support.

I Included the source files from fusion 360 so everything is editable.
