Fountain pen ink vial stand (for 15.3mm sample vials)

Quick holder/stand for fountain pen ink sample vials - fits the 15.3mm diameter vials (there also are slightly wider vials out there, but the Goulet ones, and the ones from Ebay with the little cone shape at the bottom work well).

Hexagons that are a little wider on both sides to accommodate the caps.

Printed in ABS on UP! mini, took about 50 minutes, fits if you rotate it.

Blender file also included.
