quick funnel (vase mode)

A simple funnel with air gap. If using a 0.4mm nozzle I recommend setting the extrusion width to 0.6mm.

I also included a version without air gap.

Scale to your needs. You can also cut the model in the slicer if you want to shorten something or if you need a flat side.

Set bottom solid layers to 0. 

I used a 0.4mm nozzle with 0.2mm layer height and 0.6mm extrusion width (print settings → advanced) and recycled PLA (Prusament).
