Modular Magnetic Ouchie | Stackable Fidget in TPU

So I really like TPu fidgets, they are my favourites! And I had success printing TPU. I also really like magnets, so I thought I would make my own version of an ouchie - a sensory spike fidget roller. This one is “stackable” thanks to magnets embedded on the inside! So you can print as many segments as you like and put them together in any order and colour!Printing instructionsI printed this using Overture TPU 95A and it worked great! I highly advise you to use TPU for this print because of the really thin bottom layer under the magnet, as TPU tends to be very strong and resilient, and it also does not let glue through! But you can definitely experiment with different materials. There are four plates. Each plate is named according a combination of two factors:Magnet size: both 6x2 amd 8x2 magnets are supportedBottom layers under the magnet: 1 or 2 (see assembly instructions below)Assembly instructionsEach “segment” is composed by two parts that screw in together, as shown in this pictu
