Rigid mount for input shaping calibration using BigTreeTech ADXL345 accelerometer board

Installation:
Attach accelerometer to mount using included screw and large center hole. Remove heatbreak fan, screws, and spacers. Reinstall heatbreak fan with mount in place of factory spacers.

Be sure to set y, -x, z as accelerometer axes in klipper config file.

Supports may not be necessary depending on your setup but worked better for me with them enabled.
