The vehicle mechanical platform is modeled on similar commercially available models, but was redesigned in Fusion360 as a custom platform. The acrylic was cut on a laser printer and the brass hex standoff pillars are standard dimensions.

All files for this design, including the Fusion360 model, are available on Thingiverse at https://www.thingiverse.com/majicdesigns/designs.

Motors and Wheels

The new platform is designed to work with 28BYJ-48 type stepper motors using custom brackets, shown below.

The wheels were designed to fit the 28BYJ-48 motors. The outside rim was covered in 5mm self-adhesive foam to create a gripping tyre-like surface.

Together these create an easy and securely connected drive block.
