I originally wanted to create an entire printable shelf, but figured I could use less material this way. It also enables you to construct custom (as in not strictly a grid) shelves.

I just hot-glued 12 together and it works surprisingly well. In the future, I'll probably screw them into some sort of backing for mounting. For now, I'ma just command strip it to the wall as is.

Features:

• Can hold most tapes securely thanks to the little “clip” thing (see pic of me holding the thing upside down)
  • Stacking one on top of another does not interfere with the “clip”, as it doesn't need much flex room
• “modular-lite” - you can print and use just one, or print hella and fix them all together like I did, or to a wall, or to whatever. Nothing specifically “modular”, but gluing them together is easy and effective
