Replacement of the anchor button of the Bosh Maxxomix blender arm. The button is designed with a thickness slightly greater than the original and with the faces of the smallest flexion points since this is the weak point of the piece. It is printed in PLA although the ideal would be to print it in ABS or Nylon since it is a piece exposed to mechanical stress. I have tried the PLA piece for several months and it lasts a lot if we are careful when anchoring the arm by pressing the button to anchor it since if the PLA piece is pushed directly it suffers premature wear
