CTC Printer Front and Top covers

I've bought one of these: http://www.amazon.de/gp/product/B00FHCCX3S/ref=as_li_tl?ie=UTF8&camp=1638&creative=19454&creativeASIN=B00FHCCX3S&linkCode=as2&tag=zrdfghj-21&linkId=DNOM4GZUT2DZ73Q3

And used the cover for the front of my CTC printer and the box itself for the top cover. These are the parts that I've used to fixate the cover up until now (still a work in progress)
