Funnel Vase Mode

I wanted a funnel that fulfilled the following criteria:Printable in vase mode for speed and reduced material usage.Optimised geometry to fit a standard coffee filterInner flanges to increase flow when using a coffee filterand venting holes to stop suction forces.I believe this model fulfils all these criteria. There are two versions, one with a 20mm spout and the other has a 17.6mm spout. the both use approximately 26g of filament.Both print with out supports and i have not needed to use a brim
