Dual threaded screw fidget

Threaded rod that have threads in both directions. fun fidget or mechanical demonstration.

There are multiple lenghts of threaded rod.

Depending on your printer i made nuts with 0,2mm clearance and 0,3mm clearance so you can get the fit you want, im using the 0,3mm one. please ask if you want any more :)

To get the nut in the opposite direction just mirror it in your slicer.

here is video of it in action:
