4 inch drone frame (untested)

4" prop drone - haven't tested it yet, will update when i've built it. Total weight once supports are removed is ~32 grams.

Make sure you print it with tree/organic style supports or it'll be miserable to remove them. I've designed it to print with PETG, it should be plenty stiff enough to work. The model is upside down just to make printing easier.

designed to be used with:
- speedybee f405 flight controller stack
- 4x 1806 motors
- 4" props

battery will just be strapped underneath

update 21-9-24: fixed weak point on middle support + stiffened centre bit
