It looks like this developer also extended some of @jamiek’s work on gridfinity boxes. This hose library looks pretty complex and well thought out.
Damn @azab2c, it seems the one you made might be obsolete now. 
Neat find! I’ll be using some of these, especially Chris’s Camlock adapters which seem to be inspired-by/compatible-with @bitingmidge’s work.
Jamie’s OpenScad based gridfinity generator, and interactive configuration tool got a prominent mention in one of Zack’s videos too.
Alright. I’m convinced. Chris must be lurking around here somewhere.
Oooor you guys are just pretty clever and this forum is a hub for smart people. I sometimes think so when you guys start with your maths stuff and I am just sitting there fiddling my philosophy-thumbs. 
I agree with this one completely! That’s why I love it here so much. Learn something new daily. Now if I could just remember some of it LOL. Keep hoping all the smarts will wear off on me LOL
Ohh that’s so cool! I’m with @Tokoloshe on this - I need to be able to see stuff, anything that can’t be seen to be drawn is just witchcraft.
I was not before, but am now… thanks for sharing my work.
You are correct the Camlock connector is designed to be compatible with PeterH’s Camlock hose system. I connected with PeterH on Printables where I found his work.
Welcome, new clever guy.
