Broad Sharpie Holder

I bought an 8-pack of broad/large Sharpies and, after staring at them in a disorganized mass for too long, decided to 3D-print a holder for them. Most of the designs on Thingiverse are for the narrow Sharpies with circular profiles, so I made a new design for the ones I bought with more oval profiles.

I cut a hole into the central core to save plastic, but that hole can be used to hold a few pens or other objects.

I've set this Thing up as a customizer, although there's not much to be customized. You can reduce `$fn` to make for a more polygonal design; and you can adjust `maxMarkerWidth` and/or `minMarkerWidth` to tweak the design if you have markers (or something else) that aren't quite the same size as Sharpie-brand markers.
