Smok TFW12 (810) Driptip

Hello Everyone!
I tried to clarify the dimensions. I added spiral molding to the inside. which is only design and does not play a special role.
I have been using this tip for a long time. comfortable, I occasionally change it to a different color. it became a filament color check model. only because (my own printers) it takes 11 minutes + heating time to print.
what material do I recommend?.. be food safe first. a little more heat resistant than pla. (but I used one without any problems.) but I recommend petg.
