The Bowden tube holder is for Dryboxes with a pneumatic connector.
The actual version is suitable for Bowden tubes with an outer diameter of 6mm.
The bracket has an inner diameter of 10 mm.
Inside the holder is also extra space for the filament, so that you can simply pull it out when using it again without opening the box. You can see it in the sectional view.
I printed it upside down with a layerhight of 0.1 mm and with support for the inner of the bracket.
I will soon add a Bowden tube holder for Bowden tubes with a diameter of 4mm.
