I wanted to find some piece to mount some nice metal pipes in my IKEA cabinet, but I wasn't able to find exactly what I needed. The original model was close but I needed it to be able to stand on its own, and match my 16mm diameter pipes, so here is my personal design on it.

It's very cheap, durable and looks really great and simple, just plain structure, and doesnt catch too much attention.

I also added a sunk in M3 screw hole, to make it as hidden as possible, just incase I want it to mount it to the side of the cabinet sometime.

The diameter of the holes is 17mm and made to fit my 16mm pipes, fits perfectly.
