Bi-Directional Threaded Bolt and Nuts

I made this as a challenge to myself and I couldn't believe the results. It's fantastic. Less than 13 grams too. Featuring a bolt that has a thread that runs both clockwise and anti-clockwise and a nut that runs each direction too. It's just a bit of fun and works as a fidget toy too. The bolt is 6cm tall by 2.85cm wide (the bolt head). The bolts are each 1cm tall and the same width as the bolt. Finished nicely with chamfered edges. Printed using BambuLab Basic PLA Black, BambuLab Basic PLA Jade White and ELE GOO PLA Beige. I have another version here which has a second bolt that goes in the top, to create the illusion that you can't get the nuts off the double ended bolt.
