Human: Magnetic Fingerboard https://youtu.be/zQOSJlBwET4 I'm not a skilled fingerboarding expert, but I was asked to design a printable model just for fun. At the beginning it was a challenge to create a fully working board out of really small, thin parts. I used the smallest bearings I ever saw (2 x 6 x 3 mm), equipped with rubber tires cut from a matching tube (6 x 1 mm), for some good rolling wheels. My personal highlight is the suspension. I always wanted to use magnetic force for this purpose and it works great. The resistance can be adjusted by adding different magnets (check the YouTube video). But for me the most fun is to let the board just bounce on the ground. Parts: 1. Board - 1 Piece 89.5 x 6 x 20 mm Add: - 2x Neodymium magnets Ø 4 x 2 mm - 4x Axle bearing - Edge to the outside - 1x Eyelet Axle bearing - 4 Pieces 8.8 x 6.2 x 2 mm It might be necessary to redrill the middle hole (Ø 3 mm) for a smooth axle movement, depending on print accuracy and squeezing of the first layer. Axle - 2 Pieces 20 x 19.1 x 1.8 mm Add: - 2x Bearing 692 ZZ - 2 x 6 x 3 mm + rubber tube tire - 1x Neodymium magnet Ø 4 x 2 mm - Equipolar to the magnet in the board Eyelet - 1 Piece Ø 5.6 x 2 mm I used superglue for all non-releasable connections.
