Assasins Creed Hidden Blade

Apart from the prints you will need:

-Screws:

M3 x 5mm, 2 units
M3 x 14mm, 4 units
(if you dont find the exact dimensions buy larger M3 screws and cut them with pliers, and use sand paper for the sharp edges)

-Lubricant: (optional, in case there is too much friction)

Some kind of grease, I personaly use:
Vaseline grease (but any other you consider appropriate will do, even some oils)

-Elastic bands:

15mm diameter
(I used some elastic band that some years ago where viral for making bracelets, I'll leave some photos of them)

-fishing line:

0.4mm - 0.6mm (I'm using 0.6mm)

-Spring:

you can use one from a pen an cut it to length
