If your printer and filament is not dialed in perfectly don't even attempt to print this model, it's not an easy print.

About
Everyone loves a good Voronoi diagram. So I made a pencil holder that prints without supports with minimal cleanup required, depending on printer and filament type. It does not use a lot of filament.
Print Settings
I recommend printing it in PLA as there are some challenging overhangs where it's beneficial with maximum parts cooling but it could print nicely in other filament types as well.
I've printed a couple on my Bambu Lab X1C and P1P printers and they printed very nicely in Prusament PLA without supports in around 2 hours and 20 minutes using 31g of filament.
