InkOwl Ink Holder

I recently got InkOwl's Canon Pro-300 replacement ink set to refill my cartridges' to save a bit. I wanted a stand to hold all of them securely together, but couldn't find anything that worked, either too small or wall mounted, etc. The size of the circle is 42mm with a very snug fit that they won't fall out even when upside down. The depth of the hole is about 13mm. Should work with any bottle around that size. It also fits my ProAcryl Primer bottles perfectly. If you got the ink set, check out my syringe holder as well.
