I downloaded and printed a lot of chains mounts and got a lot of trouble fitting them on the Ender 3 Neo Max for different reasons. I ended up massively modifying a lot of them to fit the machine as much as possible. I am happy with the results and I wanted to put them all together for people with this model of printer.
You'll need a couple of M3 bolts and nuts for the extruder mount and change the M3 bolt on the fan duct for a longer one.
This is based on the Ender 3 Cable chain by JWhiskey and some mounts by other uploaders.
The author remixed this model.
Almost all the mounts are from remixes of other people that I modified for this machine
