I didn't buy this print file when it can out as I didn't think it was to great. I was very wrong and now it's one of my favorites.
I do have an IDEX (Artist D) but printed this on my Prusa MK3s.
This file and "Bridges" file are great for simple layer color changes that look nice and can easily be done in the Prusa slicer.
The dovetailed fitting on the bottom of the top plate (attachment to base) is especially nice.
Great to watch the marbles, very gd file and easy to print.
Easy print and assembly. Works well as the first module in the Two Wheel machine - the dumping of 4 marbles at a time adds to the visual excitement. Nice chunk-chunk-chunk noise as the marbles wind their way out of bottom of the run.
