I’m sure the throwers of the group might have a little idea what a giffin grip is and that we don’t have one! It is a tool that you place on your wheel head and it will center your items for trimming instead of you having to do it manually. I came across a listing on Etsy for a 3-d printed tool that is very similar to the giffin grip. I was wondering if investing in the files to print our own would be something the ceramics area would want to do?
