https://youtu.be/B5lYcxHPq6k "Marblevator, Clown" was designed by our family, friends and me! This somewhat whimsical and very large Marblevator (325mm wide by 240mm tall) uses a clown to lift marbles from the end of two tracks up to the start of the two tracks. Four giraffes assist in the process. The upper giraffes are carefully aligned to gently nudge the marbles out of the hands of the clown at the start of the tracks. The lower giraffes function as gates to hold the marbles at the end of the tracks until the hands of the clown lower to catch them. We had about 22 family members and friends gathered at our home for the initial presentation of all of their input into "Marblevator, Clown" and they really enjoyed it! So if you're interested building this model and have access to a large format dual extrusion 3D printer, then prepare yourself for quite a 3D printing, assembly and alignment experience that in the end, as our family and friends reacted, you'll be quite happy with, as was I! 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 4.12.1, and 3D printed in PLA on Ultimaker S5s and an Ultimaker 3e.
