This is a remix of a remix of an OTF fidget knife.
I took the best of all worlds so to speak and mashed 'em together to create this fun little fidget toy.
Perfect for messing with coworkers ;)
It's AMS compatible and can be printed on one plate using the given print profile.
I used PLA+ for the springs, other than that I don't think there's a preferred material choice.

Have fun printing and fidgeting!
