Dremel To Proxxon Micromat Adapter for bqLabs Dremel holder

I printed [bqLabs Dremel holder ](http://www.thingiverse.com/thing:1259799) (really nice design by the way!) hoping it would fit my Proxxon Micromot.
Of course, it doesn't. The proxxon machine has a smaller diameter.
So here is a little spacer/adapter!
Beside printing this thing you have to make the hole at the front a little bit bigger. But the shouldN#t be a big deal.
