Hilbert marble run

Here is a marble run inspired by the famously known Hilbert space filling curves, with this you are able to 3d print lego compatible marble run of any size.

There are 6 different models necessary to build every iteration wanted, each of them are based on the 2nd iteration of the Hilbert curves

and also the Freecad files for anyone interested in the making of these models and who want to modify them for their own project
