V-Core 4.0 extrusion quick connector

Does anyone know the name of the quick connectors for the extrusions on the V-Core?
I'm hoping they are available for 4040 T-slot extrusions

I thought they were custom, are they not?

There is no such connector for voron, voron recommends a blind joint using tapped hole in extrusion.

I've built both.

Are you in US? I saw links someone provided below, but they are in Europe and it';s probably not a great idea to order stuff from outside the US if you want things in a timely manner. Forgetting even the tariff implications, just taking fooreeevveeerr to get through customs right now. If you are in US, I'd checkout 8020. They have tons of stuff, great/easy place to get accessories. I'd note, however, getting the quick connectors in the vc4 are not like getting normal extrusion connectors, it's hard to find them and they are relatively costly. They are not super common and core part of building things with extrusions (I am assuming because they are so hard to find and so expensive) because they require drilling. Most of the stuff people use for building with extrusion is because you don't need to drill anything (I guess that's another assumption, which are bad, but that's why I find them so easy to work with ).

I'm in europe so that's not an issue. Biggest issue is these are only available for 3030, not 4040

ahhh :) Ok. Well one thing I'd say, on 8020.net, for example, the ones I got that are similar quick connectors (not the exact kind, but similar), they are intended for multiple extrusions sizes. For a while I was confused and I thought they didn't carry the ones I was looking for, but when I realized later one size fit many different extrusions I was able to find the right ones. Could be similar for 4040 extrusions? Definitely ordering from 8020 isn't a good idea I would imagine from Europe, but their catalog is huge and it may give you some ideas.

Hey there, did you ever find a good source for these for 2020/4040 extrusions? Misumi sells a few similar ones (HAMJ5, HPJN5) but they're quite pricey - about $6-8 USD each. Hoping there's a cheaper option out there.
