Hubelino Marble Pump (very modular)

thingiverse

Part of the [Duplo Gears Project](https://www.thingiverse.com/thing:2268803). Probably only works with [Hubelino](https://hubelino.de/) plastic marbles (24.3 mm diameter). I started with the [original Marble Pump design by ewap](https://www.thingiverse.com/thing:2595333) but the parts were too big and the design not as modular as I would like. Also, I wanted to make the pump work with Duplo Gears. What you need: * One or many augers. Just put them on top of each other until you reach your target height. * One auger bottom. Alternatively you can use a Duplo Gear if you elevate the pump enough for it to fit below. (The auger bottom part is actually the axle top part generated by the [gears script](https://www.thingiverse.com/thing:2268803).) * One bottom part. Or up to four to lift four marbles in different tracks at the same time. (In this case, use brackets for stabilisation if needed.) * An outlet on top. Can't go wrong with right. * As many housing parts as you need between these to add up to your target height. A gear to drive the pump can be put at the bottom but also at the top if that's easier for you to connect. ([Use the locking column.](https://www.thingiverse.com/thing:2778700)) Or, of course, you can just connect any kind of Duplo block to drive the pump by hand. https://www.youtube.com/watch?v=FT8SnHsN-JI
