This is a simple funnel with a bent elbow.

I designed it to facilitate loading up a coffee roaster with green coffee beans.

This works very well.

Due to the high temperature environment (the coffee roaster has to be pre-heated before loading it with the beans) I have had to use ASA plastic as PLA or similar will deform once you insert the funnel into the roaster.

Printed with:

• 0.2mm layer height
• 20% infill
• ASA (I suspect ABS will work too)
• Supports (if printing in PLA you might not need them, but I found with ASA I had to use them otherwise the elbow part was drooping)
