Hello everyone and thanks for looking!
 
I am selling Antminer Z9 120mm adapter shrouds. 
 
I guarantee direct fitment – you will not find these available any where else! Designed 100% by ido3Dprints.com. 
 
This adapter mounts directly to the back of your miner using the STOCK          screws. 
 
 With this adapter you can…
          -Connect another 120mm fan to improve cooling
          -Connect a 4 or 5 inch shroud in order to link this unit to a cooling pipe or heat exchanger
          -You can connect a custom silencer such as: Dual Tip Silencer (located on this store page).
 
The item will be printed on demand when you order and it will take about  ~3-4 hours to print from the time you order.
 
Please see the screenshots. These are of the exact print settings.
