Assemble the cube make the top of the top washer of the screw align with the centre piece tip and tighten the screw 7 times clockwise 90 degrees, from there use the cube and if it's too loose, tighten each side 90 degrees or 45 degrees, vice versa. When it's all done, test each side, find which side feels the best when turned (let's call that our favourite side), loosen that until top washer line to line with centre cap while remembering how many 90 degree/45 degree turns before line to line. Then tighten it exactly the same amount of 90 degree/45 degree turns. Loosen all the other sides till line to line and tighten it exactly the same amount as your favourite side, from there play around with tensions except for the favourite side until all sides feel the same as your favourite side.
