This is a remix of AdditiveTech's great Helical Gear Cups:https://www.thingiverse.com/thing:2826950
The original base was too large for my Monoprice Mini Delta, so I needed to split it in two. I realized that I could also easily add a third (or fourth, fifth etc.) cup to the chain.
To reproduce the original base you'll only need the left and right pieces. Print one center piece for each additional cup. The tolerances on my printer aren't great but the dovetails needed only minor shaving to fit together. The bearings were a good snug fit.
