Marblevator, Baby Steps

myminifactory

A compact, spiral staircase style Marblevator boasting knobs at both ends for effortless clockwise, counterclockwise, left or right hand operation. My wife's first impression of the prototype with multicolored steps was that "Rainbow Roll" (a nod to sushi) would be a more fitting name; I'm sticking to Baby Steps. Eight millimeter ball bearings serve as marbles in this design. To see the prototype in action, check out the video here: https://www.youtube.com/watch?v=yeF4z9jjIDE. Designed using Sketchup Make 2015 and printed on a Makerbot Replicator 2 with Makerware 2.3.3.42 "Standard" Settings (.2mm layer height, 2 shells, 10% infill) in PLA material.
