Pen / Sharpie holder for 15 items

This was designed as a holder for the many, many Sharpie's we had laying around, but it also works fine as a generic pen, brush, pencil, tool, whatever holder. It has holes for 15 pens, and has 6 countersunk screw holes built in.

It keeps the pens off the workbench, but still easily accessible, and doesn't take up a whole lot of room.

I printed these on my Dremel 3D40 at .2mm layer height, without supports, and they printed fine with no distortion.
