Hey, is there a good write-up on joints for generic joints for 3d prints?

Hey, is there a good write-up on joints for generic joints for 3d prints? I am looking for more options. This is a good start, but i know there is some things missing here (specifically in edge to edge bonding)… I am over thinking a joint on a really simple model, and would like to see some options… Currently i am using pieces of filament for pins and gluing it with CA glue., but that leaves a pretty big seam i would like to hide.

Current thoughts:
tongue and grove
interlocking dove tail
puzzle cut

I will have to write up a few methods and try them out.
