Vented Funnel for a Pyrex 100ml Graduated flask

-->UPDATE: I have included a lid. Haven't printed it yet, though.

This is funnel for filling a Pyrex 100ml Graduated flask. The reason for this is to solve the issue with trying to fill it with something like olive oil or sesame standard funnel and dealing with the air trying to escape.
The channels on the outside allow the air to escape and thus the oil or whatever liquid flows in faster.
So far, it works pretty well.
