PC4-M10 Plug for 4 mm PTFE Filament Tube with Drybox

PC4-M10 Plug for 4 mm PTFE Filament Tube with Drybox

This plug is designed to close off the 4 mm pass-through hole in a PC4-M10 fitting — useful during printing, when the lower outlet of the drybox is temporarily unused.

The plug features a small hook, so you can clip it onto the PTFE tube itself when not in use. I printed a bunch of them — now they stay with the drybox instead of hiding somewhere under the table. 😄
