google translate : Because I have a second ams, it is too expensive to replace the four-channel hub buffer, so I used the bottom bracket component of the A1 mini. Of course, the price is only one tenth of the price. Cut off the excess buckle on the bottom bracket assembly and insert it directly into the PTFE interface of the buffer. Because this is a hard connection, we were worried that the shaking of the PTFE tube during feeding would damage the buffer, so we designed a fixed accessory. After the holder is printed, you only need to remove the M3 screw on the left side of the current buffer, snap the holder on, and finally fix it with M3*30 screws. After using it for two days, there are no problems for the time being, and the feeding and ejection of materials are smooth when changing colors.
