Funnel

thingiverse

This versatile funnel, initially crafted to handle M2.5-M3 screws, has evolved into a go-to tool with various applications. I'm sharing it here in the hopes that it will become an essential item in your toolkit as well. For optimal results, print this funnel using your slicer's vase mode, which enhances its compatibility with liquids. The exit diameter measures approximately 12mm. I've also found this funnel to be a valuable addition to my small desktop trash container setup, particularly when dealing with resistor leads and support material. If you're interested in creating a similar system, I recommend checking out the "Mini Trash Container" on Thingiverse (https://www.thingiverse.com/thing:2739251), which can be easily adapted for this purpose by simply flipping it over.
