Here's a new version of the 3DClippy filament cutter that allows for a vertical orientation. It's installed on the SV-06, but can easily be adapted to other printers, like those equipped with the Creality Sprite extruder, for example. https://www.youtube.com/watch?v=iHTxQTIqE2o

This eliminates the need to do any tip shaping, which can a) reduce the headache of trying to get a particular filament to work correctly, and b) can speed up the whole process significantly.
It's totally open source, so please, take it and adapt it to your own printers... just make sure you share the design for others to use!
