Brother P-touch TZe Modular Cartridge Storage

These are connectable storage containers for the Brother P-touch TZe tape / label cartridges.

I looked around for a good solution for this and was unable to find any. Those I did find were set for a specific number and size of cartridges or were expandable but required gluing together.

What I needed was something that was specific to each size of label cartridge and that could be attached together and detached from each other. I also wanted them to be aesthetically pleasing and to fit snugly.

What I came up with so far is the perfect solution for me (although I suspect it may be the perfect solution for others as well).

I currently have three sizes [12mm, 18mm, and 24mm (the ones I had on hand to measure off of)] but I am more than willing to design to other sizes as needed and make those available (just message me and I'll usually have the new size produced that day if you can get me accurate measurements).

Enjoy, I hope this solves this rather annoying problem for many other people.
