Noctua C14S Cover and Holder for Fan´s

Hello all =)
This is my first "Big Projekt" made in Tinkercad.
My idea is: A Cover that looks great and funktions at the same time, by moving air Completly trough the Cooler. No Erly escape trough the side finn opening.
Top can be mounted a 140mm Fan and Bottom defently should be a 120mm or a 140mm.
I need to print this as next but share it first, so maybe changes will come. If not, Text will say.

EDIT: I put in the "Grid" so you can print it in different Color and put it in (So i hope)
Also the Design had some minor issues, also the Bottom 140 GPU Mount holes have now space to mount the Fans with a rubber holder.
