The assembly is simple. Print the parts (1 off for each of the larger components and 2 off for the bearings) and assemble as in the photos.
If you want to use a steel bearing, you can replace the printed one with an unsealed 609-9-24-7 bearing. A sealed bearing might have too much friction.
Works well with reverse bowden setup. See link: https://www.printables.com/model/667034-neptune-4-reverse-bowden-upgrade
