https://youtu.be/6Z6h0yEibpU "Marblevator, Marble Launch Mechanism" was designed as a test mechanism for an upcoming project of mine, but the grandkids liked it so much "as is" I decided to publish the mechanism just in case you, your kids, your grandkids, family, friends, etc. liked it as well! The attached video illustrates as the number of magnets are altered, the height of the marble flight changes. 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 and Tough PLA on Ultimaker S5s.
