I was going through some of the free designs I had downloaded a while back. One had an interesting joining method. Using friction instead of glue. I figured I’d work on it a bit and see if I can make something a little better.
Introducing, self locking tabs. Just slide together until they pop into place.
Still needs a bit of tweaking, just a tad more play than I was hopping for.
Here’s the SVG if someone wants to play with it too.
