Locking Tiles (IRL Pixel Art)

I designed a pretty simple way to lock tiles together. I saw quite a few other locking tile designs on here but they all were a single piece, which I wasn't a huge fan of because then the outside tiles have the joining piece hanging off the edge and don't form an edge that looks flat when viewed from the front. I also didn't see any that were small enough for what I wanted to do (the pixel art pictured above).

Each tile is 15mm x 15mm x 6mm, and the joints snap into the back at just a little bit more loose than a "friction fit." They'd probably work pretty well scaled up, but I'm not sure how tight the fit would be.

If you'd like to check out other things I've made, I recently (early June 2021) started a Twitter account where I share projects I've done. https://twitter.com/makingorwtvr

Printing:

IIRC for the tiles I used 0.2mm layer height and 15% gyroid infill, and they came out to be almost exactly 1 gram of filament each. I used the same settings for the joints.
