A6 Fan/Sensor Bracket with M12x1 threads

This is a barely modified re-mix of https://www.thingiverse.com/thing:2703848 which is itself a re-mix of https://www.thingiverse.com/thing:2424312 I added M12x1 threads to the hole that holds the sensor in place. The fine 1mm pitch threads on the sensor are made possible by having matching threads in the holder, allowing for precise adjustment. For example, after measuring you decide the sensor needs to be lowered by 0.25mm; simply rotate it exactly 90 degrees and you know the exact amount you have adjusted it. Note that the threads can be very tight but loosen up after repeated use - specifically, putting the sensor in and out a half dozen times. Here's a helpful hint: the sensor comes with two nuts and a lock washer. Place these on the sensor and jam them together tightly to create a good grip so you can turn the sensor into the plastic threads without cross-threading. Be extremely careful not to cross-thread, as it is very easy to do with these fine 1mm pitch threads. I used Fusion 360 to replace the hole in the STL file with an M12x1 threaded hole. Everything else was left unchanged. A STEP file is included for anyone who wants to create yet another remix. Printing: I printed the small mounting tab at the bottom, the one with the two counter-sunk screw holes, with 95% infill and extended it upward into the bottom frame. The rest was printed with 40% infill, 1mm thick top/bottom and walls, resulting in a very stiff and strong part. To be honest, the bracket works just fine without threads.
