Let's make some stuff which is both compatible to Duplo & Hubelino: [marble run](https://youtu.be/potXXApGO2I) Buy at [Hubelino](http://www.hubelino.de) or print a duplo compatible marble track set: like [joachim67](https://www.thingiverse.com/thing:159219), [thecrash74](https://www.thingiverse.com/thing:994812), a marble collector from [wuz23](https://www.thingiverse.com/thing:333603) and some extensions from [soundTricker](https://www.thingiverse.com/thing:2473498). ###2 Dual color marbles: So let's first print some 2 color marbles (with text) and measure them: * Hubelino marbles: 24.2 to 24.5 mm (measured 4 balls) * Printed 2 color marbles: 24.1 to 24.8 (measured 6 balls) Okay, need to sand them a little bit better and should have calibrate both nozzles before printing, anyway, the printed balls do roll nicely over the tracks. ###Simple wedged tracks: Ofc we need more tracks. Going for sense & simplicity, I like these tracks from [wuz23](https://www.thingiverse.com/thing:12255) a lot. So decided to do some laser cutting on this one, although these could also very simply be printed. Could be used w/o elevation height, since there is a wedge shape inside, which makes the balls roll anyway. Added 2 versions both dxf & stl. Making these from maximum 4 mm plates. ###Flex track v7 (updated 20181201): Add some more 3D tracks for your marble run: the marble flex track. Printed some flex tracks, which works fine. Using: PLA; 0.8 nozzle; 0.2mm layer height. Version 7 is flexible from design and does not need special materials. Version 5 is also still available, see the nice TPU make from Gogo83 and hd42.
