The face plate is made by a german company.
(also in english)
I live in Berlin
You can download a wonderful CAD-like program on their website. It is their own product, so you only need to upload thee data it creates and you will have your faceplate a few weeks later. Very easy! It's only difficult to measure every hole exactly... But I could give you my file if you want to try it.
Here a screenshot:
I postet some more fotos in the "pictures" thread on page 43...
The faceplate made 95€ incl. shipping. 5x Blue Velvet made about 60€.
The Mixer I bought on ebay for about 60€ I think...
All together <250€
Oh, I forgot the knobs:
I replaced all of them with Sifam knobs. Sifam comes from UK but maybe you find a local distribution. 10 big knobs cost about 30€.
