Kobayashi Fidget Cube (Infinity Cube, parametric)

thingiverse

Just another toy to keep your hands busy. This one is fully customizable, allowing you to scale it up or down, adjust the gaps according to your printing skills and equipment. I included three examples in STL format: - 20 mm (regular) - it takes 5 to 6 hours to print on my A6. - 15 mm (small) - should fit perfectly into a child's hand. - 8 mm (ultra small) - 35 - 45 minutes. This is definitely not for beginners. See https://www.thingiverse.com/make:474097 for some valuable hints. The decoration line can be used as a measure to change the color if you want to obtain a dual-color cube. I included some helper models that can be generated: - *cube* - the entire fidget cubes readily assembled - *hinge_test_vertical*, *hinge_test_bottom*, *hinge_test_top* - two cubes and a connecting hinge. - *hinge*, *hinge_hole* - a single hinge and its hole for any purpose. - *gap_inspection*, *gap_inspection2* - a cross-sectional view of two cubes and two hinges. It's only used to check whether your customization will break something inside the cube. - *hinge_profile*, *hinge_hole_profile*, *hinge_gap_profile* - these 2D profiles determine the shape of the hinge and its hole. - *cube_profile* - this 2D profile exhaustively determines the optics of a single cube's surface and edges.
