I am just wondering if you can achieve something similar with extruded aluminum
Maybe. I doubt it though. It’s more than standard extrusions. There are cut slots thruout that allow the accesory conections in the crevices of the slots that need to be rectangularly shaped.
This is not a dumbass device. It looks simple at first glance, but it’s not such. Well built and desingned. It is not an easy copy on your own imo.
There’s a reason it’s not cheap in any market including their own home country. A little over priced…yes. but super over paying for this I don’t see it as such after owning one for five yetars now.
