@mooklepticon I print almost exclusively with PETG and what I have found that works for me is to dry the filament, even if coming right out of the package. With some filaments, decreasing the nozzle temperature also helps.

@Rutty For something that will be chewed, I wouldn’t use TPU (or other filament) since it is very hard or next to impossible to get information about 100% of the ingredients of a filament and confirm that they are safe for consumption.
For the same reason, I use 3D printed items only with room temperature food, e.g. a coffee bag clip with spout.
