#2A big advantage of this technique is that the assembled model is 'isotropic'. If it was printed in one piece, it would be easy to split along the layer lines.
But when printing the plates separately, every face is equally strong.
Great project!

#3This is cool. This is also massive. I wonder how much e.g. the arcade machine housing costs just in the filament used, and how many hours did it take to print.

#4> "The strength comes from the tightening/wedging effect when pulling the join apart. If the dovetail is tapered, the join can also tighten when it aligns too – this is highly desirable for gluing, as it means the glue will not be scraped away."
While true, dovetail and other traditional woodworking joints borrow their strength from using the wood grain to support the joint.
I don't know a lot about 3D printing but I'm guessing a lot of the assumptions about woodworking joints strength aren't applicable.

#5I been thinking an openscad->cura pipeline would be cool. This post is very similar and inspiring.
Imagine running a custom action or pipeline and getting a physical object pop out in the shed. Pretty awesome.
I also like the idea as git as the way to share and remix 3d printing instead of (as well as) the various STL sites.

Interesting. I didn't know that.
But I do know about 3d printering. :)
Strength in printing is usually a function of the mass used to print with. So more plastic used at the boundary layers will mean stronger joints.
Eg. A PET plastic soda bottle (pepsi, coke) will flex in the body where it's thin, but not on the threads on the top of the bottle. In fact, those are pretty strong, because they need to hold on a cap which keeps the carbonation in.
A good question to ask is if the dovetail joint in plastic as strong as wood? The answer may likely be no, but it may not also need to be. It just needs to be "good enough". And this looks like it might be.

I kinda want this in the slicer, like prusaslicer.

#8A linked-to inspiration for this — printing an arcade cabinet for Atari's Space Race (1973) — is a great watch too: https://www.youtube.com/watch?v=SONO6LTHuR8

#9Oh man, now I totally want to 3d print a full sized interlocking Han Solo in Carbonite with embedded magnets to stick on the front of my refrigerator!
Maybe I'll have to get huge commercial refrigerator for the proper effect, but it will be worth it.
