Hi all, I wanted to try some simple object with a moving part, and so I designed a cube with an embedded sphere. The difference of radius between the sphere and the spherical hole of the cube is 0.5mm (the diameter of the sphere is 2cm). I ordered two prints of the same model with different materials. I received my first prints, and here are the results: [list type=disc] [*] the one in Tranparent Detail material is perfect: the sphere is freely moving inside the cube (and I can spend a lot of time playing with that ) [*] The one made of White Strong & Flexible material instead is just one solid piece, with no moving part :cry: . [/list] I have seen topics about wall thickness, but what about "void" thickness? I mean what is the minimum amount of space you should have between 2 objects to be sure they will be disconnected ?
