Gridfinity Bin for 16mm Diameter Ink Sample Vials

This is a 1x2x4 high Gridfinity bin that will hold up to 8 ink sample vials with a diameter under 16mm. The vials seen in the photo are 15.2mm in diameter and commonly sold through major fountain pen enthusiast sites. MEASURE THE OUTER DIAMETER OF YOUR VIALS before printing this model. This was designed for use with 16mm diameter vials I purchased off JetPens and Amazon.
