DDS Funnel

thingiverse

With the addition of an SiC insert to my switch, I found it difficult to get crumble into the insert without it falling out around the outside of the cup. This funnel has a lip so that the tip can sit in the insert without pressure fitting into it and pulling the cup out with the funnel. It has a smooth inner wall so the crumble wont get caught, and a big enough opening at the bottom so it shouldn't get clogged. The top fits snug enough against the rubber grommet to keep it sturdy but not tight enough to stick.
