Marblevator, Magnetic Tracks.

youmagine

I must admit that my original reason for purchasing a 3D printer was to create marble machines of unparalleled complexity. My first masterpiece, the Marblevator, has been making waves online for over six years now. Since then, I've designed, 3D printed and assembled an impressive array of marble machines using Autodesk Fusion360, and it's high time I updated my original creation to feature a more expansive staircase, base and tracks that can accommodate actual glass marbles (12mm) with ease. Plus, neodymium magnets at each track section end will allow for effortless, snap-together track assembly. To cater to the diverse needs of marble enthusiasts, I've created the Autodesk Fusion360 File "Marblevator Tracks.f3d", a parametric track section generator that's included in this tutorial. By simply adjusting two parameters - radius for curved track sections (right and left) and length for straight track sections - the track sections will be instantly updated by Fusion360, ready for 3D printing. In this comprehensive guide, I'll walk you through the process of assembling the Marblevator and a simple track. However, with the "Marblevator Tracks.f3d" model at your disposal, the possibilities are endless - limited only by your imagination! As always, I've probably forgotten to include a crucial file or two, so don't hesitate to reach out if you have any questions. After all, I'm not immune to mistakes. Designed with Autodesk Fusion 360, sliced using Cura 4.2.0, and printed in Ultimaker Tough PLA on an Ultimaker 2+ Extended, an Ultimaker 3 Extended, and an Ultimaker S5.
