This is a redesign of my previous model for a funnelholder at work. The hole for the funnel is 1.25cm in diameter and have a nice glide in to grant stability. The holder works as a “hat” on top of your flask so that it is stable. It has four airventelation ducts so to make the liquid go through the funnel faster.

The holder have a airhole so that liquid have free flow through the funnel
