This is a link post Rather interesting design
if you have a 3D printer and a need for it, you might like this

This is a normal post It's a nice solution, havent seen similar
I'd be tempted to seek ul certification and apply for a patent myself, but noble that he's sharing. Wasn't sure how getting electrical cert applies to 3d printed material, but apparently there's a process as long as you use certified material.
About the only thing would be water/damp proofing, but I saw at the end he had a version that left a gap for solder, so this could also be taping or those heat shrink socks

This is a normal post It's maximising contact surface area
Which is great for mechanical strength but I'm not sure it's best for the electrical connection - it's unlikely to clamp with enough force to give a gastight joint. The modern allegedly maintenance-free connectors like Wago have a very thin knife-like contact.

This is a normal post these can be printed (don't have the metallic springs like the inline wago ones), and seem strong in the vid
they are quite chunky, a drawback if you're connecting multiple wires in a confined space, but I can see their utility and cost effectiveness for some uses. But they're not certified, so you're liable if your house burns down because of them.
its an interesting point about the squeezing. it's a trade-off between grip strength, connection, and starting to get resistance which can be dangerous. He has made it so you can grade the gap for wire sizes, but does the clamshell pressure start to reduce the cross-section as it's mostly going to applied on one axis?

This is a normal post "Stronger than solder"
Not to be too nit-picky, but making a solder joint that's stronger than the wires themselves is not particularly difficult.
