Marblevator, Armed (but not dangerous!)
myminifactory
This Marblevator is indeed armed to the teeth with an arm mechanism that lifts marbles from the end of the track and positions them at the beginning of the track, but it's not a menace - unless you get too close and a finger gets in the way! The tracks are interchangeable, and I'm working on some brand new ones. Check out the video of my prototype here: https://www.youtube.com/watch?v=PAVz1Sx7UTg. I designed this baby using Sketchup Make 2015, and it was printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" Settings - that's .2mm layer height, 2 shells, and 10% infill.
