Funnel for Quest M3 coffee roaster

This is a remake of Hiroko Price's funnel (kitahiro921). Her design is great, but seemed just a bit fragile to me. Besides, I wanted to learn how to design something like this in FreeCAD, so I created my own version. The wall thickness on this one is around 1.2 mm, a very small increase over the original but enough to make it a bit stronger (on my printer, anyway). I also added a small lip to the top to make that edge a little bit more robust.

Thank you so much Hiroko for the original desi
