I wanted to use an ADXL345 to measure resonances in Klipper in my Ender-3 V2 glass bed, but there is no easy way to attach it, so I designed this quick mount that will allow you to get the accelerometer aligned flat with the bed to avoid any vibration dampening effect.

There are 3 holes for M2*8 screws, ideally you should use at least 2 screws to ensure that the mount is completely secure against the bed.

My recommendation is to print it UPSIDE DOWN (orient the model so that the 3 holes are facing up) with support enabled:

• Support structure: Tree
• Tree support branch angle: 50
• Support Overhand Angle: 55
