4mm Filament PTFE Tube Cap

I designed this cap for use with my Upgraded SOVOL SH01 Filament Dryer, which switch its filament outlet with a PC4-M6 coupler. This modification allows me to secure a PTFE tube to the dryer and feed the filament directly my printer. The cap works with a short piece of PTFE tube to plug into the coupler, keeping the dryer box airtight when not in use. This helping to maintain proper storage conditions for your filament.
