Heatbreak bowden fitting (6mm)

This is a bowden fitting to secure a standard 4mm PTFE tube around a 6mm threaded heatbreak. It utilizes one of those compression fitting things from a standard bowden fitting. OD is 5.5mm.

There are no internal threads on this, it is sized to self-tap itself over the heatbreak. Shrinkage was compensated for 5% (ABS used). There is a lip on the inside where the fitting will lock in place. Mine holds really well.

It is 9mm tall with a 2.5mm deep fitting lip; if your printer is calibrated to a different shrinkage rate, it would be easy to just make your own based on this info.

##Tolerancing

**Fitting hole**: 5.5mm - (5%) compression tight fit + (5%) shrinkage = ~5.5mm
**Heatbreak hole**: 6mm - (1%) thread tight fit + (5%) shrinkage = 6.2mm

**Disclaimer**: YOU NEED TO HAVE A HEATSINK or some type of setup where the heatbreak will not get hot around the fitting.

Standard bowden fittings like the one pictured can have a 6mm male thread which threads
