Funnel w/venting

I needed a couple of funnels to use in the kitchen, and although there are many to choose from here on Thingiverse, I couldn't help but design my own. This design has ridges that keep it from sealing when used with a bottle or jar. It will always vent along the sides.

I printed it in three (3) sizes: Original, x 1.5, and x 2.0.
