I loved samuel's original design, but only had mason jars laying around so I remixed his with mason jar threads replacing the 4 prong type used by jelly/spaghetti jars.
I also rotated the drain holes within the center of the juicer to align with the slots of the uprising arms in an attempt to resolve some pooling I noticed in the original design. Haven't fully tested to see if my changes helped or not.
Two files, one with built in support and one without to use your own slicer's support options. If you generate your own supports, I highly recommend only supporting to build plate to avoid a mess of clean up in the center part of the juicer.
