Description
This design mounts the BIGTREETECH (BTT) ADXL345 2.0 accelerometer board (https://www.amazon.com/BIGTREETECH-Accelerometer-Klipp-er-Connection-Stealthburner/dp/B0CHJQ6CXF) to the bed of the MK3S+ or any bed that is under 5mm thick.
Use a shim or thick tape between the sheet and the end of the bolts if you want to prevent marring the sheet.
Stock firmware does not make use of an accelerometer and requires 3rd party firmware such as Klipper.
To assemble you will need four M3 nuts and four M3 screws (8mm seems to be the sweet spot, but you can use shorter for the board and longer for the bed).
Print with a good amount of infill (50%) for rigidity.
