3d Printed Air Balloon Motor for LEGO

You can see the explosion diagram here in 3d viewer (Sketchfab): If you’d like to print it, you can get all the files on Thingiverse: :4197583 If you don’t have a 3d printer, but still want the motor, you could try ordering it on any online printing service, like - Grab file on :4197583 - Drop it onto - Settings: process - FDM, material - PLA or ABS (didn’t test the second, but should be a bit better) - It showed me a $20 price with delivery (which is about 1/6 of the price of my chinese 3d printer, with delivery as well).
