Saw other double threaded bolts on thingiverse, but the nut wouldn't thread all the way down to the head, or the proportions were off... so I made one.
it's 3" long, with 1/3 tpi thread one way and 2/3 tpi the other, and an OD around 1.50 in. Especially if you print it with the nuts 100% infill so they're heavy, it's really fun to play with in the hands.
