Stick on anywhere you feel the need for Input Shaping and make it vibrate.
Easy for users with multiple printers.
Above all you won't need any consent from the printer, just the Klipper firmware.
So what are you waiting for???
Just shove that (ADXL2040) in my hole and make it vibrate.
Variants:
V1 shoves it in deeper but is a gaping hole.
V2 just inserts the tip and its holds it tight, also smaller. (Recommended)
Don't know what else to say…. its just a holder clip… jeez stick it with… well… I don't know maybe Double sided tape, VHB, hot glue or whatever…its your life. Do whatever.
