Marblevator "Mini", Zigzag Edition Track
myminifactory
A Twisty Track for the Marblevator "Mini", Bowl Edition base. Video of prototype here: https://www.youtube.com/watch?v=Una3DxiP2_o. If I counted right, eight marbles (9.5mm or 3/8" ball bearings) were on the track. Works great with 1 to 8 marbles at 1.5vdc, and 1 to 12 marbles at 3vdc (although at the higher voltage, you might lose your grip). Uses the base assembly ("Base.stl", "Gear Crown.stl", "Gear Motor.stl" and "Gear Worm.stl") from the original Marblevator "Mini", Bowl Edition. If you've already built the Marblevator "Mini", Bowl Edition then simply push out the worm gear and track, then install this track assembly and replace the worm gear; takes about 20 seconds or so. If not, build the Marblevator "Mini", Bowl Edition first. Prints in two pieces that snap together. And finally, if you don't mind manual labor, a hand-cranked version is available. Printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" settings.
