Printable Check Valve

thingiverse

During the summer, I decided to design a check valve as a temporary replacement for one of my things. This is the result. The valve worked perfectly in stopping water from flowing in one direction and required only the plunger to not be directly printed. In order to make the plunger, I printed out a mold and then filled that mold with silicone and let it sit. To release the mold, I cut away at the seam using wire cutters.
