12mm Bowden Tube Clamp 4mm tube

This is an easy* clamp for a 4mm Bowden Tube.

The outside diameter of this clamp has a 12mmx1.75 mm thread.

Please note the model is set to 11mm diameter to allow for tolerance in the nut grip.

NOTE: This may add a bit more friction to the filament, (1.75mm), as it passes through this part because this uses more of a squeeze than the dig in barbs like a standard pneumatic push fit does.

• I found standard pneumatic push fit caused the Bowden Feeding Tube to become trapped by the teeth barbs inside the pneumatic push fit fitting and made it difficult to remove the tube..

I pulled on the Bowden Tube with as much force as I could...

It does not pull the Bowden Tube out, which is how it should be while the nut is on...

Also includes a nut grip to fit better, easier grip, etc...
