E3D V6 Clone bowden to direct drive adapter insert - fine thread

thingiverse

This adapter fits E3D V6 hotend clones for Bowden extruders, perfect for Direct Drive applications. It centers and supports 4mm PTFE tube from extruder to heatsink's 4mm tube hole, ensuring a secure connection. After finding Bratan's insert online, I decided to print it out. Unfortunately, the threads didn't match my V6 clone, so I had to take matters into my own hands. Bratan's insert has a 1.5mm pitch, which is too coarse for my hotend clone. I took a closer look at the pneumatic fitting that came with the hot end and noticed it should have a pipe thread. The outer diameter was 9.35mm, so I used G 1/8-28 (G9.728X0.907) thread to match it perfectly with my V6 clone. The adapter's overall length is 9.5mm, with the threaded section being 7.5 mm long and a center hole of 4.3mm in diameter. I've included a picture for reference, showing one insert next to the pneumatic fitting and another already installed in the heatsink. I hope you find this adapter useful!
