The mold I made with my own AMS has been adjusted many times, and I feel it's in the best condition now.

It's more convenient to use a Teflon tube with an inner diameter of 2mm and an outer diameter of 3mm.

Note: The outer diameter of the AMS is 14.4mm, which refers to the outer diameter of the disc-shaped object at the inlet, that is, the inner diameter of the inner circle of the shell. Moreover, the central circular hole of this device is not the center of the circle. Students who need to re-create it are kindly reminded to pay attention to this detail.
