Marblevator, Take the Stairs!

"Marblevator, Take the Stairs!" is my latest Marblevator. While I indeed could use the exercise derived from stair climbing, I decided this was much easier and watching it in action would provide similar results. No? Oh well... Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA on Ultimaker S5s and an Ultimaker 3e.
