Funnel -

thingiverse

I've designed a robust and versatile funnel for various applications. Two prototypes are available, each featuring a unique design. The first model boasts a 18 mm diameter funnel, while the second has a 14 mm tube. In both cases, the top diameter measures 90 mm. The wall thickness of both models is consistently 3 mm, ensuring a sturdy construction. I'm currently using these funnels to pour resin back into their molds without any spills or drips. However, they work just as well with other fluids and fine materials such as sugar, coffee grounds, metal components like small nails, nuts, and bolts.
