Small(ish) Problem

So while fiddling about with the claw, a wheel fell of! The connection bolt between the motor and the gear part of the bought in gear motor had been shaken loose. This normally would be a simple job of screwing it back in. However, because of the way I had glued the wheels on, I didn't have access to screw it tight again.

The wheel in question with the rim filed away

I had two options, either try and take the wheel of the motor or file away some of the rim to get access to the screw. I chose the latter because taking the wheel off has a high risk of shattering the rim and making it unusable.

After much filing with some needle files, I got access to the screw and re-inserted the wheel with gearbox to the motor.
