The started building process of my third topcover design is slowly taking shape:

After some printing (roughly 60h) there's some progress visible...

Some impressions:

All parts are designed in a way that there are minimal supports needed as you can see in the picture above. This angle without support and 0.2mm layer-height is no problem at all. 

The back portion of the topcover is printed and assembled and I think it could look good. I didn't order the panels yet because I want to see if I'm fully satisfied with the look of it.
