This V6 Assembly is all metal, and has a top opening suitable for accepting 1.75mm filament. It is not compatible with a Bowden tube system.
Note: The Heatbreak has a PTFE tube in the lower end right above the nozzle.
The part is nicely desing, but it does not fit on my CR10S as it require 3/8 in hole with tread at the top of the heatsink to connect tubing. It is unfortunate no picture show this view of the hot-end as it will have permit to detect the incompatibility.
Excellent customer service excellence shipping great products great company I'll use them again for sur
