SuperEllipse1

I've published a few box type containers before, but they all had straight sides. Some had rounded (filleted) corners which I liked better. Recently I found a 2D shape called a super ellipse which is similar to an ellipse, but with both rounded sides and rounded corners. So I thought I could use a version of that to make a nice looking box.

When the box was complete I realized it needed to have a lid, so I used the same super ellipse for that, and added a handle that also has an elliptical part on top. Both STL files are included here. The bottom printed in just under 16 1/4 hours, and the top in about 3 hours. For both I printed at 90 mm./sec and a layer height of 0.200 mm.

After designing a few containers like https://www.thingiverse.com/thing:5441646 I thought it would be worthwhile to use that technique on some older designs that had plain sides. This is the first one I picked because I u
