Paper Mate Flair Pen/Marker Holder

Recommend 3 perimeters and a brim.
If you would like the pens to fit a little bit more loosely, you can scale the model up to 100.1% or 100.2%

The non-spiralized version has a little bit more extreme angles because it doesn't have the overhangs of the spiralized one, but is still printable without supports. It is best to use a slower profile or decrease the outer wall speeds to something like 50mm/s
