Show off your favorite pens while keeping them within reach!

This is a 4x2x3 Gridfinity display case for 4 fountain pens. It also works for ballpoint pens, pencils, small screwdrivers, and similar implements.

If you need a smaller case, check out the single-unit version that holds 2 pens!

The case is 3 units high, and it is fully stackable, with or without pens. It has capacity to hold pens of a maximum diameter of 15.8 mm – this was the largest diameter that I could fit without increasing height or compromising stacking.

The case fits into the Gridfinity grid using a custom design inspired by @grizzie17's Gridfinity Refined and @rekk's Gridfinity Refried. You can push 6x2mm magnets in the nice press-fit magnet slots, or use a thumbscrew for a more permanent attachment. The thumbscrews printed from @grizzie17's files will fit this model, too.
