TPU dry-box filament grommet

Feed filament out of a sealed dry box

Drill a 14 mm hole in a dry box or a cereal container lid and push the spigot through: the 4.2 mm bore grips a 4 mm PTFE tube airtight, so filament feeds straight from the dry spool to the printer without letting damp air back in.
