This is model 1 of 3 designs inpired by others out there.  For this one I used a rechargeable battery from an electric toothbrush with usb charging point.  Similar ones are used on bike lights sold on Ebay which could be adapted.  I wanted to try to get all wheels the same diameter using gears and this added an extra visual element to the design.   Drive is from a dual axle miniature electric motor and gearbox sold on Ebay and other sites. The top can be glued on once the wiring is complete.  Add a weight to the front end to and it will climb inclines.  Rubber band tyres in grooved wheels were used for increased friction.  Print with support for axles and body upright.  Instructions for inserting the motor on my other video.

Motor STL for anyone who wants to adapt the ideas.
