2 liter bottle funnel top

thingiverse

This is a modification to Theidd's funnel that I made so that it would funnel birdseed into a bottle-based bird feeder. The hole is MUCH larger, and I removed the hanging loop. It should work well on sand and other powders. Instructions This will print without needing support, so it won't need a lot of cleanup. RomanoGaspari has told me this is based on his grabcad design; I got it from Theidd's funnel. If you are going to do anything commercial with this you should attempt to contact the originator!
