After serveral years of usage the ceramic mill element getting loose, so I replaced the plastic insert thats holds the ceramic part tight.
It fits tightly so depending of your printer you may scale it a bit up or use a bit of sandpaper if it not fit.
This is for the WMF Ceramill https://amzn.to/3lvUKo6
I've printed it in PLA without any special settings
