3mm T (staggered) Tile Spacer

This is a 3mm tile spacer for staggered tiles. We used 18 of them remodeling our kitchen as seen here!

I modeled it after the shape of the store bought ones. Again, they only work when staggering tiles - sort of brick style. They were lightweight, cheap, and worked perfect!
