Wide Rectangular to Circular Funnel

I needed a wide funnel to fill some jars with pet food. I had already designed a Wide funnel for this, but because it was circular, it kept rolling and falling to the floor.

To solve this problem, I made the wide part rectangular. This prevents it from rolling and keeps the funnel stationary when placed on the table.

These are it's more relevant dimensions:

Printed in PLA and PETG, without rafts or supports, at 0.2 mm resolution and 100% infill.

I would say that the best position to print it out is upside-down, just like this:

Since it would presumably be a part that will get a lot of use, I think it is advisable to print it in PETG or ABS for a more durable model.
