[CC0] Parametric funnel

This is a simple & functional funnel made in openscad. It it designed to be compatable with almost every printer. It has automatic detection for when an angle is too steep, and warns you about it. We made this model public domain, because we believe in being open and allowing anyone to use existing ideas for how they see fit. If you like our works, please consider supporting us by purchasing from our online store: https://laserology.net/ Ideally print this with PETG, or other chemical resistant materials, depending on the use case of the funnel. If this will be used for food contact, plese print it with PETG, use 100% infill, and place it in the dishwasher after every use. This should take care of any bacteria.
