AntMiner 4in shroud 120mm base

I saw a lot of choppy vent shrouds on here for the antminer that had a lot of ridged sides. Here is one I made with some CAD software that is smoother and has a nice transition. This will work on any of the AntMiners from Bitmain with the 120mm fans. Just bolt and go. Do not sell my design. Make your own if you want to sell it. Thanks.
