Expandable Tracked Vehicle

This is a 3D-printed tracked Vehicle. It is designed based on the concept of building blocks, so it can be applied to different main control boards and can also expand different functions/modules. The profile "Chassis Module" contains all the 3D-printed parts required for a complete chassis. You need to prepare 2 TT motors, 4 M3x25mm screws, 4 M3 nuts, and 2 M2x8mm self-tapping screws. Screws and motors can be purchased in the Maker's Supply, but please pay attention to whether the plugs are compatible with the main control board you are using.The design of the tracks adopts the concept of print-in-place, which can significantly reduce the assembly steps. Each track can also individually wrap the wheel hub, forming a complete wheel.I'm using a micro:bit main control board, so I've also provided the parts for assembling the micro:bit. If you're using a different main control, you can refer to my assembly dimensions of the holes and pins to build your own building
