Sharpie Rack for 8 Fine/UltraFine Double-Ended Pens

I've run out of space, really :o)

I have a pack of double-ended Fine/UltraFine Sharpies which were cluttering up my desk or drawer or shelf depending on how tidy I was trying to be! Neither was satisfactory, so I designed a rack that could hold them UNDER the shelf, so occupying effectively no space at all (hehehe).

It's fine for the single-ended Fine Sharpies, but it's rather too loose for the single-ended UltraFine Sharpies although they will still be stopped by their cap clip. It doesn't fit the Retractable ones though as they have a significantly thicker body and they only go into the holes a small distance.

The idea is that the pens go all the way to the point where the cap joins the body and then stop. So the rack can be mounted on the underside of a shelf like I wanted, or even on the front face of a desk or shelf for extreme ease of access!

I would have preferred two holes for screws but there isn't really room for 2 screw heads so I just did one, a bit of double-sided sticky tape can be used between the unit and the mounting surface to resist twisting if that happens. Sticky tape on its own isn't very good at sticking to PLA, especially upside down where all the weight of the pens and holder are constantly trying to pull the adhesive off. The mounting hole provides clearance fit for a 3.5mm thread diameter screw, that's what I happened to have available.

Print in supplied orientation, no support needed, the only overhang is the top of the screw hole which prints just fine.
