This project was well-developed by Tulio Laanen. I am looking forward to more of these in the future!
Please note that slicing with Cura is very important because XYZware's slicing left it rigid and with extra friction, and I had to file and sand the track down for optimal performance. This project is very time-consuming and the base alone took 14 hours to print. But, if you are up to the task, then prepare yourself for a fun marble run to brag about!
