Description
Here’s a little caddy I designed to keep my inks tidy and ready for action. It holds nine 5 mL test tubes (I use these from Amazon), plus a 10 mL J. Herbin bottle and a 15 mL Pilot Iroshizuku bottle.
I made this because I love using dip pens and glass pens for testing colors, but I didn’t want to risk contaminating a whole ink bottle when switching shades. The 5 mL tubes are perfect for filling—but they’re wobbly on their own. This caddy keeps everything upright, organized, and ready to go when inspiration hits.
Got different bottles in your collection? Drop the dimensions in the comments and I’ll happily whip up more print profiles to fit.
