The cider press is an older technology that has been used for ages to make juices from fruit. The cider press enabled people to move from manually crushing fruit via a mortar and pestle or even two rocks to a self-contained unit that produces more juice in less time. This allowed for the production of cider and other pressed juices at a commercial capacity - beyond subsistence farming. This extra revenue generated from commercial sales of cider can sustainably elevate people from financial poverty and produce a healthier local economy.
The goal of the 3D-printable cider press is to provide an affordable means of efficiently pressing cider. With scaled-up designs, the press can be used to produce enough product to sell excess not used for subsistence. This design fulfills the need of enabling financial mobility. Simple cider presses have been made by the | Low Technology Institute. However, even these designs require pre-cut wood,fasteners, and precisely-threaded rods. These parts can usually be found in hardware stores, but these establishments are not prevalent in 3rd world countries.
The cider press as presented in this page is modeled to fit on a standard mason jar for demonstration purposes. The openSCAD files are parametric and allow for easy customization of the components.
The size of the whole assembly can be scaled to be used on any cup or even buckets.
The spigot can be modified or removed for alternate cider press configurations when the outlet for crushed liquids is at the base of the
The press base can be modified to incorporate different patterns or crushing heads.
Threading can be added to the collar (as seen in the example below) to form a tight grip on any cup or jar. These can be removed or replaced as well.
