Picture story Radio panel

I try to build the mechanics of the volume buttons with cheap ballpoint pens. 
Here you see the collection. I bought this for only 8 EURO from the german discounter LIDL. 
The red part in the middle is the mechanics, I´m using for the panel. 
Knobs and gear wheels are molded out of PU. 
The rest will come soon!
