Marblevator "Mini", Counterclockwise Hand Cranked Base
cults3d
If you wanted to build the Marblevator "Mini" series but hesitated because you didn't want to buy motors, connectors, power supplies, batteries, etc., and then have to solder the whole mess together, then this thing may be for you. This is a counter clockwise hand cranked base designed to work with the three Marblevator "Mini" tracks; Bowl, Seesaw and Zigzag (for a clockwise cranked version, see this thing: http://www.thingiverse.com/thing:313944). The photo is shown with the Marblevator "Mini", Zigzag track, but the video that follows shows all three tracks. Caveats: it does require finesse in building and a very steady hand in operating, but if I can do it, so can you as shown in this video https://www.youtube.com/watch?v=ZIS4EiZXx2s. Printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" settings.
