Nema holder for Ultimaker quiet retraction

I made this thing for the excelent Ultimaker quiet retraction by Maxy : http://www.thingiverse.com/thing:53690
It's a very good upgrade, very usefull, but with the weight of the nema 17, the upgrade became brittel and I didn't want to print an another on. So I imagine this thing. It add again some noise but less than the wooden backplane...

I also add a fan holder on it for the nema17...
