bfm1012uh-azl adapter to rd40 nato air inlet

Couldn't find it anywhere, so I made this It doesn't perfectly match the top surface of the fan I don't know how to draw it It seems like I should find the center from the back of the fan and then draw an elliptical variable-diameter spiral line Hoping someone interested can help

I can't draw threads, I took that part from a derivative work's prototype

When buying fans, be wary of Shantou washed goods and shipments from Jieyang are generally not right either These places have a lot of knockoffs, refurbished items, washed goods, and so on

The bottom-left and top-right holes were made according to the specifications of bfm1012uhff8 The top-left hole can be seen on the bottom surface, or by removing the top surface The top-left and bottom-right holes were positioned using calipers, and the measurements were calculated by deepseek Actual testing shows it can be installed on other 9733 fans This thing should be able to screw onto an 8cm fan However, the bezel might not be quite right, and the large washer is even less so

Prepare your own washers Inlet outer diameter 38-39mm, inner diameter should be a bit larger The outlet for the part is a 6800 large washer The mounting position I drew has an inner diameter of 63.5mm, an outer diameter of 80.5mm, and a depth of 1mm The genuine washer is made of red foamed silicone

The intake fan doesn't work very well I screwed on the Jupiter A2P3 canister (there's also an adapter, search for it yourself), and the current dropped from an unobstructed 6A to 1A Perhaps PWM cannot be adjusted to full use The airflow hasn't been measured yet, and I haven't made the part to adapt the exhaust to a ventilator hose Perhaps I should add a 1-to-2 RD40 head and then use two canisters

I used JLCPCB's free PA11 MJF for printing I suggest applying a layer of food-grade silicone yourself to prevent loose fragments that can be wiped off by hand The volume of the model I provided is just enough for the free coupon By the way, do I really need to raise that intake section
