Hello Danny, now that I have the box in my hand. I am wondering if the box should not be upside down so that the ventilator is on the top? 

I assume that you want to blow hot air out, and that will rise. The ventilator could of course blow cold air in but that way you also suck in dust that tends to be at the ground. 

Nothing prevents me to put the box upside down, just your cool blue stripes would be hidden.

Cold air in, Hot air out :-)
That was my intention, you can turn it upside down. It was a hard job for your printer, you work with one extruder? That will be the problem, other printers use a second material for the structures that can be resolved. It has a better connection with the heating bed. Then you have printers with a closed enviroment  (heating room). It's because I use it for bussiness tasks I could buy a professional machine, you can not compare it with the home versions. There's a real difference in quality and strength.

There is an upgrade for multiple materials but this one I only have one extruder. 

I did not start this Thor project because it was easy, but because it was hard :-) That is where you learn the most.

I just simulated the case will be 13H print, the case cover will be around 8 hour print. I may print it this weekend. 

Hello Danny, I already printed most parts but the big box is about 13H job. So that one is postphoned untill I can find 13H were I can be near my printer. That is no sooner than next week.

I am looking forward to see the result : - )

this looks awesome well i bet you know what your doing could you look at my project and ,maybe get advice?

It is christmas! Thanks for that beautful present.

Files online :-)

Already printing the 2 sides (4 hour print) wondering if it will fit on my 3D printer
