Eva 3 fan 4028 inlet and cover

It is a first iteration and not tested yet. I will appreciate any comments which can help further modifications. The goal was to make a new inlet fan model for 4028mm fan without any integration to Eva 3. The fan inlet is designed to be used with 4 heat insert M3 x D4.6 x L4.0. The top cover is designed to be screwed with M3 screw to the back Eva 3. You can try to add heat insert (both side or one as you prefer) to the Eva 3 back (ideally as in the picture) or pass through M3 screw. 

It was design to be used along with EBB42 mount.

To print: 

I used 0.2 mm layer hight with 3 perimeters. Fill density 15% should be sufficient.

For the fan cooling inlet you might want to use the support threshold 30 deg should be fine.
