Marble Pump

Açıklama

Just a marble pump, do nothing style. Marble pumps have been around for years and, most often, are made of wood. I've made quite a few out of wood, but each time it required "whittling" to make it work. With a 3D printer, no whittling is required (well, except for a few stray strands in the arches). Video of just a marble pump here http://www.youtube.com/watch?v=p9qddnKNb-E. Uses 14mm size marbles. The photo and video show the marble pump motorized, but the motor is not required as the crankshaft can easily be spun by hand (maybe someone will add a handle?). Printed in PLA using Makerware 2.3.3.42 ("Standard" settings) and a Replicator 2. This assembly is a test for a larger project. UPDATES: 1) "Someone" (me) added a handle and a minimized base. Vrack requested a handle for the non-motorized version of Marble Pump. The files "Handle.stl" and "Base No Motor.stl" have been added as requested. Haven't tested them yet.
