Description
Let your (and your kids) creativity flow free!
A fully 3D printable chassis for your cardboard box balloon powered car, requires no hardware and prints with no supports, only 26g of filaments and fits the A1 mini.
Just cut and paint the cardboard however you like, and the chassis will propel it!
Easy to blow up the balloon from the nozzle at the back of the car. If there is too much air leakage around the balloon you can add some tape, but I've not needed it to secure the balloon or to propel the car.
