Oil udder oil filter draining tool - GIF and video

If anyone is interested in the development process, seeing as this is homemade tools, here are some photos of the development process. The final parts are injection molded but we did all of our prototyping using urethane/silicone and molds we 3D printed. The main nitrile rubber component is molded inverted as you can see in the pictures to save on tool cost. The combo plugs (red) we still mold ourselves.
