Rail mouting system for STUVA enclosure

I needed some tool holders for my 3d printer enclosure so i made this rail system with pegs that slot into the hole pattern inside a Ikea STUVA enclosure.

For now i have only made a simple half circle cup to hold som misc. tools, but i will make more as needed.

I've included part drawings if you wanna design parts for the rails.
