This is a mount for a ADXL345 Accelerometer to clamp onto your Cartesian style print bed. You may need to remove your plate that you print on so that the clamp will fit. In addition to the printed part you will need 2 M3 brass threaded inserts with an outer diameter of 3.75mm,
and 2 M3x12 socket head cap screws. Assemble by using a soldering iron to press in the inserts, and then mount as shown in picture. Print at 100% infill.
