A 3D Printed Air Pump for the balloon powered mechanisms I design, print, assemble, test and publish.

An o-ring is used for the piston gasket, and shelf liner for the intake gaskets. Petroleum jelly is used for the lubrication.

A tall version (shown in this video) and a short version are available.
