Raspberry Pi 3 cooling case MK2

I was tired of cases with fans, blowing air down on the heatsinks and just letting the air circulate.
Why not having the air go thru them and away?
So that's what I was going for.

This is my 2nd attempt. Now with a "clossed" design. Adding a bottom part and editing the top a bit. Hope you like it, let me know in the comments.
