This simple pen organizer prevents your pen collection from getting messy by holding them together in groups.
It is modular, grips your pens firmly and is very stable.
You can measure the diameter of your pens and scale it inside your CAD or slicer software. The standard version is made to fit most pencils and pens on the thinner side (7 - 8mm diameter).
It works perfectly as both PLA and PETG.
