Small car with elastic tractionNo support printingNumber of prints :1 X Elastic support frame1 X Frame lower platform1 X Wheel with lug for elastic band2 X Chassis2 X Front Wheel2 X Rear Wheel2 X Axle 12 X Axle 211 X Front weight wheel10 X Rear weight wheelThe rear axle weights act as pulleys to roll the rubber band.Front weights are added according to the printing density to hold the car to the ground (they may not even be necessary).This model can undoubtedly be greatly improved and redesigned, to reduce weight and axle friction.Make sure that everything fits together and that the axles turn freely in their housings.Hook the elastic band to the "Elastic support frame" and to the "Wheel with lug for elastic band", roll backwards, then release.I'll no doubt be making modifications to the wheels in the future, so that I can place rubber bands or elastics around the wheels for extra grip.Don't hesitate to leave a manufacturing comment so that I can improve my model.
