Summary

To better understand how a 3-axis accelerometer works and what kind of data it really measures and returns, I printed this little mounting for the ADXL335 accelerometer sensor.

The 3 axis are labeled on both ends, the letters can be made more visible with permanent marker.

The other STL is a slightly smaller object which I mounted to the servo (see video).

Please watch the video to see how I used it to visualize the basics of an accelerometer to measure angles.
