Notes:

The spring tension may vary between filaments. I used Hatchbox PLA which did the trick, but PLA plus may be the better option for durability although it is untested.

There is a replacement spring printed in the 3MF file, since they tend to wear out after extended use.

This is V1 of the filament flinger and there may be small issues that need attending. Please notify me if you find any issues and I will try to rectify them as soon as I can!
