Vented Funnel for a Pyrex 100ml Graduated flask

thingiverse

UPDATE: I have added a lid to it; however, it is yet to be printed. This funnel is designed for filling a Pyrex 100ml Graduated flask, addressing the problem of air escaping while pouring liquids like olive oil or sesame using standard funnels. The exterior channels enable smooth flow by allowing air escape, enhancing the efficiency of the process. The funnel has been performing well so far. To use it, simply print it out; a low infill is sufficient as there is minimal stress on this part.
