Balancing FPV Bot

I'm working on a 3D printable frame for a Balancing Robot.
Also i am going to add FPV to it, just because we can ! :D
This still is a work in progress.
Rims are done. ( 5mm dia. shaft with flattened side )
Put a piece of inner bike tube aroud the rims.
Working on the frame.
I have build the bot with what i had laying around, could use smaller steppers.
These are Nema 17 steppers. Which fit this frame perfect.

The hardware and firmware where designed by Joop Brokking.
