Note: If you downloaded the version posted before 5/16/19 5:05 PM CDT, please download the new file. I accidentally uploaded a previous version that didn't have the correct thread spacing. I got this idea thanks to my father's habit of stacking several custard dishes with each day's breakfast/lunch/dinner/bedtime pill/supplement cocktail. He dropped and shattered his stack of cups the other day, and I thought...hey, nested PETG cups won't shatter...and if I put threads on them they're even travel friendly! At around 60mm the diameter is similar to larger pill containers. Nice knurling for grip. Print two or more, in different colors for different times of day if you want. A stack of four will end up roughly 60x90mm. They nest together perfectly. I purposefully left about .5mm of slop in the custom threads so that they'll interface smoothly but not excessively tightly. Minimal thread length means only a bit over 1 turn to separate. I printed at .15mm but you could probably get away with .20mm.
