This is a fancier version of Tween1 (https://www.thingiverse.com/thing:5455000): I added the surface decoration of small hemispheres and tweaked the overall shape a small amount to make the transition from a circular bottom shape to a top that is a filleted square more obvious. I also added a rounded lip to the top edge.

This container printed in 19 1/4 hours using a print speed of 100 mm/sec and layer height of 2.03 mm. For this print I used PrusaSlicer's standard triangle infill pattern, so it required a few more hours to print than Tween1. There will be a Tween 3 with 11-pointed stars in place of the hemispheres.
