goBuilda compatible flexible wheel

This was designed as a substitute to a gecko wheel from goBuilda. The idea was to use a flexible wheel as a claw/grabber for a robot. This allows a motor/servo a range of force when grabbing a piece. It was specifically designed to pick up the FTC Into the Deep season samples, and works well at this. It is compatible with the 8mm grid that goBuilda parts use, and is meant to work with CR servos. ***Print in TPU or another type of flexible filament***
