Excellent design for the AntMiner S9. I was planning on designing my own, but thought I'd check Thingiverse first. Printed many of these and they work great with 4" ducting. Many thanks. Will send a small token of appreciation in BTC!
I have a Y-adapter I haven't posted yet that will slip over two shrouds so you don't need as many hoses! Should be up tommorrow.
Thanks! Glad they worked for you!
