Its a knife with a long chain. In the file its 100 links but you can of course expand it. Using a keychain laying around. You may have to use supports for the knife. And with that its done.
i used 15% infill and i think around 0,2mm-0,18mm of layer height.
this is one of my first ever projects so hope u like it
might upgrade it
The author remixed this model.
i used a keychain circle to hold them toghether.
