Compact pen holder for ikea skadis t-nuts

I am running out of space on my Skadis board so I had to design this compact pen holder. 
As allmost all my skadis add-ons, it uses T-Nuts for Ikea Skadis Pegboards system from 6d6178. 

It is made for 3 pens with a maximum diameter < 12mm. 

What you need:

• 1 x M2 T-Nut, M2 nut and M2 12mm or 16mm screw
• 3 pens of your choice < 12mm
