PolyBox PTFE adapter

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4674313.

I am using the Polybox for storing and using my filament but the way the big 6mm ptfe tubes are attached to the box are really poor.

To fix this I designed an adapter to connect the 6mm ptfe tube to a pc6m10 pneumatic connection.

The hole being 8 mm in the box, the adapter consists of a bottom part M8 screw with a hole inside connecting to the top part receiving the pneumatic connector.
