Hi. Today we worked on finding parts for our project, the screw-propelled vehicle, where we will make an all-terrain small remote-controlled vehicle, with screws for wheels.

After a lot of research, we found we were actually looking for plastic nylon spacers and were able to find a good match from boltdepot.com
