Marble Pump to build a Hubelino Marble Machine

thingiverse

For my godchildren, I designed and 3D-printed a Marblepump. The marble pump is compatible with Lego/Duplo bricks and built to work seamlessly with Hubelino marble tracks. I created a short video that showcases the first impression of this innovative project. Check it out here: https://youtu.be/UdZP1RB9AnA If you're interested in getting your hands on the Hubelino marble run, I've included an affiliate link for easy access: http://amzn.to/2gon6T8 As explained in the video, I came up with two distinct versions of the Marblepump. The main difference between them lies in how they feed marbles into the pump. Version 1 (fed by a generic Hubelino track): * Auger V1 * Pump housing V1 Version 2 (fed by an optimized marble track): * Auger V2 * Pump housing V2 * Feeding slope V2 Both versions share some common parts, including: * Crank short * Crank long * Spacer block * Top outlet right * Top outlet left Before printing the Marblepump, I recommend starting with a sample brick to fine-tune your printer settings for a perfect fit with generic bricks. You can find this test brick here: generic brick for testing. Enjoy exploring and building!
