Hobby Chassis Arduino

This chassis design is unlike any other. It comprises only two parts which makes it easier to assemble and print. It has enough space to fit an Arduino and many modules as shown above. I know it is a good design because I built one of my projects on this chassis and it got selected for WRO nationals. It can also be used underwater as it can maintain traction on any terrain. It uses Johnson Grade A metal gear motors at around 200 rpm along with tank treads (the model in the pictures is a bit misleading as it contains a living hinge and a few design changes for that specific modle )
