When buying a Bigtreetech pad 7 it comes with a BTT ADXL345 which is not easy to fit onto the printer depending on your model. For the Elegoo neptune 2s I had to use the BLtouch mounting screws to make sure it was nice and tight onto the gantry. It reuses the screws of the BLtouch for the X axis. The Y axis is simply a clip.
It is a very simple design but the dimensions and design are clear of any obstacles. I have included the step file if you need to modify.
I used PLA, 15% infill, 0.25 layer height. I also used M3x6 screws to mount the ADXL onto the adapter.
