Drybox Plug with Filament Buffer - for PTFE / Bowden Tube

A simple print that is used to close the end of a PTFE/Bowden tube. The special feature: The plug has a buffer for the filament so that you can easily pull it out of the tube after you pull the plug off.

I use this plug with my (dyna) dryboxes. I no longer have to open them to use the filament. Simply pull off the plug, grab the filament and insert it into the printer.

Features

• Fits 4mm tubes
• Easy 10 min print
• Only 1.5 grams of filament

Print settings

• No special settings required
• Works perfectly with PLA
• If you are unsure about adhesion: Use Brim! (I printed on a Textured PEI Plate and had no problems)
