ADXL345 Fan Mount

thingiverse

This is a simple bracket to mount an ADXL345 sensor to a 40mm fan so it can be used for klipper input shaping. I designed it for the super cheap modules from amazon / ebay but I also included a version for the much nicer Adafruit module. It uses two 3mm x 5mm x 3mm heatset inserts. This is very customizable, so you can use it to attach pretty much any module to a fan as necessary, Shouldn't need any supports. DO NOT attach it to a running fan! the vibration will throw off your reading. I am using it on the part cooling fan on a matterhackers pulse dxe. Edit 7-30-21: I have added a v2. I noticed on my particular fans that the mounting holes are inset and the bracket would be stressed if put on. I added a parameter to change the depth of the inset: if it's a value above 0, it will cut out a section of the bracket to match and reorient the part for easier printing. I also made the overall dimensions thicker to prevent any sort of flex while doing input shaping tests.
