This model uses the commonly available 2 axle motor and gearbox found on Ebay. I have made it so it is powered by 2 AAA batteries and it uses a mico miniature switch for on/off. My design has animated pistons and features large wheels with traditional spoke designs. Grooved drive wheels allow for rubber band tyres for grip. A hitch can be printed and glues in the desired position. I used mini magnetic balls for the hitch. It will pull nicely and if a weight is added to the front in the cutout (I used a 10mm ball bearing) then it will easily climb up inclines. I printed it using PLA+ silk filament and I would suggest using support below the axles. Instructions for assembly are similar to my Youtube video for my 2nd model so watch that one. Inspiration for all 3 models comes from what others have made and published but I has entirely designed these 3 models using ProDesktop 8 and Tinkercad.
