This is a very simple fidget toy that contains 2 pallets that slide around each other with a pin in between them keeping them together. Assembling this fidget is very easy, just connect the half pallets together to make 2 full pallets, I'd recommend using superglue to fuse the half pallets together. After you have assembled the pallets just insert the pin in between the intersecting side slot gaps of both Pallets and that's it! I do recommend printing this on a smooth build plate to decrease friction.
