Gridfinity based pen organizer I designed to organize my pens and other rod shaped implements I use daily. 

The two tone concept was heavily inspired by AndrejG's Bauhaus tray design.

Print Settings:

• Well calibrated printer
• Regular Gridfinity settings, I use 3 perimeters and 15 percent infill
• You can vary the color of the cup insert so it differentiates the cups and like… looks cooler
• Filament is polymaker PLA
