Update Feb. 12, 2024: I redesigned the jar slightly: the threads are coarser, and the logo is embedded so no supports are required.  If you aren't printing dual color, print the jar only and use supports.  [At the moment my X1C has a 0.6 nozzle which doesn't print the internal threads well at all.  I will upload a print profile based on 0.4 nozzle at some point.]

I designed this little jar to hold a pack of 10 single use eyedrops as seen in the photograph.

If you print the OLD logo version, use supports and add a color change at 0.60 mm.
