WARNING - This thing might be too addictive for your fingers to handle!

Made a addictive fidget toy that you can play with in many different ways. It consists of a large double sided bolt and a round nut both with 1mm pitch angle threads (same as standard M6 bolt). The bolt has a hole going through it in the size of a medium sized finger.

I have found 23 different ways of how to fiddle around with it, how many ways can you find?

IMPORTANT!! You have to pause your printer sometime in the middle before it prints the second bolt head to screw on the round nut and then resume the print. (Or if you dont know how to do this abort the print before the second bolt head and print a seperate bolt head and glue it on)

Print with smaller layer hights like 0.1 - 0.2 and print the nut with 100% infill to get it as heavy as possible, it will spinn longer then. The tolerance of the nut and bolt are 0.15mm in the files but you can use "Horizontal Expansion" or similar settings to get the tolerances higher or lower.
