I want to make my own rack, and I could just buy this stuff on Amazon, but ultimately I want to know what the rest of the world calls it so I can shop around for a better deal since I think there’s something of a “modular” tax when it comes to materials like these. (extruded aluminum I think)
I found out that they’re usually called “Z Rails” in the modular world and apparently they also go by “T-slot” or “V-slot” elsewhere.
So now the goal is find a source cheaper than eurorack vendors. Hopefully there’s a decent delta between raw material suppliers vs the DIY vendors I’ve mostly found so far.
