Warning:

This is extremely silly, and is meant more for the novelty than to be seriously used as a scraper…though it totally works, and if it gets worn out you can replace just the blade!

However the OTF design is likely not meant for this much stress, so be careful!

What I modified:

Modified the fake knife blade to be a basic filament scraper

Re-arranged to two plates

Labelled all the parts in English

Assembly Video Link

Recommendations:

Watch the assembly video, doing it wrong may damage the springs or blade, and they will break easier.

Don't use matte, silk, or other funky filaments for the springs - they need to be strong.

Don't put a ton of stress on it, and maybe only use as a backup scraper ;)
