Let's create some compatible Duplo & Hubelino stuff, like a marble run shown in this video: https://youtu.be/potXXApGO2I. You can buy it at Hubelino or print your own duplo compatible marble track set, such as joachim67's https://www.thingiverse.com/thing:159219, thecrash74's https://www.thingiverse.com/thing:994812, wuz23's marble collector https://www.thingiverse.com/thing:333603, or soundTricker's extensions https://www.thingiverse.com/thing:2473498. ### 2 Dual color marbles: First, let's print some 2-color marbles (with text) and measure them. Hubelino marbles are 24.2 to 24.5 mm in diameter (measured 4 balls), while printed 2-color marbles range from 24.1 to 24.8 mm (measured 6 balls). The printed balls roll nicely over the tracks, but they need a bit of sanding and calibration before printing. ### Simple wedged tracks: More tracks are needed, so we're going for simplicity. I like wuz23's https://www.thingiverse.com/thing:12255 tracks a lot, so I decided to do some laser cutting on them. Although these could be printed, they could also be used without elevation height since there's a wedge shape inside that makes the balls roll anyway. Two versions are available: dxf and stl. ### Flex track v7 (updated 20181201): Add more 3D tracks to your marble run with the marble flex track. I've printed some flex tracks, which work fine using PLA, a 0.8 nozzle, and a 0.2mm layer height. Version 7 is flexible from design and doesn't need special materials. Version 5 is also available, featuring a nice TPU make from Gogo83 and hd42.
