Because a heptagon is the best polygon!

A rather simple desktop organizer made using a set of heptagons

The printing effect of using double-extrusion PLA with a silk texture is very good. I set the printing speed of the outer wall to 40mm/s to ensure consistent glossiness.

Other settings can be left at their default values. No support is needed.

Please note that this desktop organizer is quite large and weighs about 175g. To prevent it from tipping over, you'll want it to have some weight. This desktop organizer is very sturdy.
