Dan’s Teeth

Teeth tend to be one way and wear even faster than nodes. That thread is useful though.

If it were me, I’d look into making self-locking tabs that grab. Oh hey, look at that, it was me like 2 years ago.

Simple locking tab joints

I wanted to make a way to lock a structure together that was fairly strong and could be dissembled with no tools. This is an early (very rough) prototype of that effort. [image] [image] I refined the design to use smaller pegs and a more robust rounded center tab in a holiday gift, but the prototype pieces illustrate the concept pretty well. The whole thing was cut out of birch ply. If you attempt something like this beware that hardwoods will break very easily across their grain. Orient a…

But that’s not what you wanted. There’s a writeup of this somewhere. Hang on.

Aha, here we go. I did similar joints to these, you can probably adapt it to work for you since you know your way around nodemaking. I actually did it with nodes that grabbed on both pieces, it was extremely strong. I swear I wrote that up. I’ll have to dig deeper.
