Also have the problem your Mid part has broken off and can't properly fix your cube anymore? With this snap on you can play once again with your 'old' rubiks's cube. -Print this part -In my case the cylinder was still around the metal pin. Remove this plastic pin until you only have the metal pin and the spring left. -Easily snap on this new part into position -Assemble your cube again -And enjoy! -(replace your old mid sticker to the new one) (after few movements your cube is running smooth again like it was before)
