This is a modified version of https://www.thingiverse.com/thing:3630098. My wife thought that container would be good to hold the spools of thread she uses with her sewing machine. But the container needed to be larger (lots of spools) and not so tall so the colors of the thread would be visible. Naturally it was trickier than I expected to make these design changes, but I finally got a design that worked.

This container printed in 14 3/4 hours using a print speed of 80 mm/sec and a layer height of 0.200 mm.
