I modified the form for the possibility of screwing together with an M3 screw. I used TFC Silicone Rubber Type 3 HB Heat Resistant silicone and it works perfectly, PETG no longer leaves any debris on the nozzle. I used 1.89 grams per mold, which is 1.7 milliliters. Mold and holder is printed from PETG with PLA as support material. There is a small stop in the mold and in the wiper holder, which prevents the silicone wiper from sliding out towards the purge chute.

New bracket for X1C using the screw from the original cleaner. Use the print file for the X1C, there is a bracket with integrated supports, then remove them. Insert the screw into the hole (as in the photo), then screw the holder into the poop chute with the help of an Allen key and then insert the silicone cleaner. If it's difficult, use a little oil.
