This is a 3d printed fan shroud that I designed and 3d printed myself. It is made from durable ABS plastic, and allows you to connect a 125mm flexible duct to your miner's exhaust, allowing you to vent the hot air directly outside (or in winter, into your air conditioning ducts).
The mount features a negative taper, such that pulling on the duct increases the clamping force.
You will need 4 50mm M4 machine screws, and a 125mm diameter screw clamp to fasten the ducting on.
Colour will depend on available material, but will normally be either grey or black.
Price is AUD $15 each, plus $9 postage for any quantity (within Australia only).
Payment accepted in AUD, BCH, ETH, LTC
