Airflow block for modular 19" 2U System

Datacenter fanatics wants to block cold aisle from warm aisle - this will make you able to do that if you haven't filled the 19 Inch Modular Rack System.

I printed it with 3 top layers and 3 bottom layers which makes it solid - but it shouldn't matter as its just a brick with two holes in it really.

You can make it a little more fuctional by adding this: https://www.thingiverse.com/thing:5702699 that can be used as cable management :)
