Plastic 3d printed nut files?

musicalstash

Has anyone got any experience with  the plastic 3d printed nut files up for sale in ebay? 

Looking for a cheap set for a couple of project and cannot justify spending £60+ for a set.

Can’t imagine them being hard enough . . .?

Welding tip files might be better than plastic ones.  There are a bunch of people on Amazon who sell them as nut files.

It's probably worth investing in a decent set though.  They should last you a lifetime with light use.
