I found TomoDesign's Joy Fidget earlier today, printed one out and thought I'd try remixing it to fix a couple issues I had.
First off, its a great model! Simple printing, easy assembly, novel design on the spiral spring and fun to play with. I had some printing problems with the overhangs on the fillet on the bottom of the bottom part, so I made mine with a chamfer. Next, when I put the parts together, they didn't want to stay together and had to be glued, so I made my components a threaded assembly. Lastly, I wanted mine to be just a little bit bigger.
I printed mine at .2mm layer height with stock PrusaSlicer Prusament PLA settings, no support necessary. I think using an aligned seam is the best option for objects like this and the threads seem to work better with an aligned seam rather than random seam placement.
Props to TomoDesigns, I encourage people to print their original design along with my remix!
