This is a ducted cooling system. Name sums it up.

It's designed to attach to a 20x40mm V-Rail.

the fans are Sunon 40x40x28mm MagLev (GM1204PQV1-8A) https://www.amazon.com/gp/product/B00118ZWYY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

The tubing can be any 1" ID spiral pipe, this is what I used: http://www.ducting.com/ambient-air/dehumidifier-ducts/pvc-flexduct-general-purpose-blue.html

NOTE: On request I have assembled this using standard CPAP hose, it works fine but with less airflow.

The cooling shrouds are missing, I am waiting on the delivery of my dual tool Flex3Drive before I can get the measurements going; However, the intake/exhaust manifolds should bolt onto any 40mm fan housing.

UPDATE: I have added the lower intake model as well as some images of the system installed and running. I will likely create some kind of hose clamp to keep everything in place and to arrest vibrations. I will post the stl when I have it finished :)

UPDATE: I added an intake manifold for a smaller format AC unit. This one has some threads I am experimenting with to make hose connection easier.

UPDATE: I also added the hose clamp that I have been using to keep everything neat and tidy :)
