CAD of Elegoo Tumbller robot

I am very pleased with how the robot turned out. There were plenty of bumps in the road, I was judging most of the geometry by eye and my Solidworks Task Plane glitched into the bottom of the screen. I was able to alter a microcontroller from grabCAD to fit the necessary geometries. The tray and the motors where done by simple extrusion processes. For some reason I had difficulty mating the ultrasonic sensor to the actual micro controller. I may add more detail to the battery pack and ultrasonic sensor as the project develops. I think the final render looks great, now I need to focus on a stabilising mechanism.
