Description
This design replaces the extruder idler with one that has mounts for the BIGTREETECH (BTT) ADXL345 2.0 accelerometer board (https://www.amazon.com/BIGTREETECH-Accelerometer-Klipp-er-Connection-Stealthburner/dp/B0CHJQ6CXF) for use with Klipper firmware input shaper calibration.
It is not a full-time replacement and is only intended to be used during input shaping calibration. You must reinstall the original idler for printing.
To assemble you will need three M3 nuts and two relatively short M3 screws (6mm, 8mm…10mm might work but I haven't checked).
