Twisty Toy

I designed this simple twisty toy based on an epicyclic bar angular transmission. It's a cool little fidget toy that looks like it shouldn't turn. Works well as a stress reliever!

3d print the two twist-toy barrels and clean/drill the holes with a 9/64" bit so that the brass rods insert and turn easily. Cut seven 5 inch long 1/8" diameter brass rod pieces and bend them 90 degrees in the middle. Then insert all of them into one of the barrels first; and one by one into the second barrel. Nice little puzzle right there! To make the toy permanent and prevent the barrels from slipping off you can use CA-glue to glue a couple of short stops onto the two center brass rods. That's it. You are ready to fidget during your next Zoom meetings!
