Chiron direct extruder - Heatsink duct, drag chain mounts and beefed up base mount

thingiverse

This is a remix of frozenrc's version of the chiron direct extruder. I designed a different cooling duct for the hotend heat sink which snaps into place around the v5 hot end and it has a small duct on the side to blow some air onto the extruder motor. This duct has a small lip which butts up against the extruder gear body to keep it in place. EDIT -- I redesigned the extruder bracket because I found the 3d printed base moved too much along the y axis. So now you will reuse your existing metal mount to mount the hot end. Then bolt up the new bracket to mount the titan extruder above the hot end. I made it quite tall to give you a bit of leeway with the small piece of bowden tubing. Anything shorter looked better, however it was a pain to disassemble. Then I designed some different drag chain mounts. The one on the hot end I will not lie is a bit of a pain to install. It will require 2x M4 x8mm long SHCS with nuts. The two original bolts that mounted the drag chain to the stock location can be used to bolt up my mount in place. The other drag chain mount gets bolted into the old stepper motor mount location on the right side of the frame. 4x M4 x8mm bolts and nuts will be required.
