The Teflon tube came out of the BMG Dual extruder regularly, because the neutomatic connector that it has from the factory only has [4 teeth] to hold the tube. So I made this adaptation so I could put a [12 teeth] pneumatic connector inside the BMG Dual Extruder.
This adaptation gave me excellent results, the teflon tube has not escaped again.
You only need:
1 Connector Pneumatic PC4-01
1 Plastic strap.
Impresoras 3D Puebla PLA
Wait for the piece to cool if you touch it can be deformed.
If the support you printed does not fit well, you can cut and shape it with the cutting tongs.
Support made in Tinkercad.
