Base

- Rounded the corners of the bed where the motor gear sits to avoid it getting stuck
- Increased the size of the motor cable hole
- Removed supports for the motor driver
- Replaced arduino mini/micro usb aperture with a cable hole. Nano can be powered on pin 27 by a 5V source so the same cable can be connected to the motor. to power both. I recommend keeping the parts easily dettachable to program the arduino.
