Originally designed for moving M2.5-M3 screws around, this funnel has become pretty general use for me. Sharing it here, where, hopefully, it can funnel your things too.

Print using your slicer's vase mode for best results (this makes it more compatible with liquids).
Exit diameter: ~12mm

I've also used this as part of a small desktop rubbish container (when clipping resistor leads and support material). If you're interested: https://www.thingiverse.com/thing:2739251 is a container that works well enough for this purpose (just flip it upside down).
