Air propelled Car
by DocTatur, published
A simple balloon powered jet car designed with Solidworks and builded with a Replicator (1.75 filament, 0.4 nozzle)
built four weels, four axes (A.STL), four hat ( which should be put at the axes end) and one car and your done !
use low infill ( I use 0.17) for the car to improve thrust-to-weight ratio :)
put a little balloon on the top tube, blow in the rear opening to inflate it and ...fire !
