Ender 3 Extruder and Hotend Bullseye Duct Compatible Mounts
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
I wanted a way to run a chain from the extruder to the hotend that would work with dpetsel's Bullseye duct (https://www.thingiverse.com/thing:2759439). I started with sandpit's Cable Chain Extruder Mount and modified it to give the extruder lever arm more room to move. I narrowed and replaced the mounting point he used with one of johnniewhiskey's chain links so that the fitment is now perfect. Then I added an additional chain mounting point courtesy of hanananana's modified extruder mount. Finally, I adjusted hanananana's modified hotend mount so that it will work with the Bullseye duct. I also made sure that the chain will be level on both ends.

Update
----------
• 2019.03.18: After seeing two people post that he had issues with the length of the mount being too short for their particular setup, I have added two longer versions.
Versions
------------
• The normal length should work for most people. The z axis screw lined up perfectly on my Ender 3.
• If the normal version doesn't line up for you, I have added a +1.5mm and +3.0mm length version you can use instead.
Printing Notes
-------------------
• If your printer setup and filament can do good bridges, you can print with with supports touching build plate only, otherwise you will need to set supports to touch everywhere.
• Turn off Support Interface settings if you are using them and instead…
