Marblevator, Buckets.

"Marblevator, Buckets" uses a carefully timed two bucket lift mechanism to transfer 11mm nylon spheres between the end and the start of the track. The track starts with a large downward spiral segment that transitions to two straight segments, all designed to move spheres from the track start to a marble gate. A marble gate is incorporated into the design to hold the sphere in position until the lower bucket arrives to pick it up. As usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes. Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 14.12.1, and 3D printed in PLA on Ultimaker S5s.
