I took a look at admin's "Benchmade 62 balisong butterfly knife M3 fasteners" and I was inspired to make it just a little bit cleaner.
So I hid the m3 nuts in the blade and the handle.
and added a cool circuit board look and a tanto blade :D
You'll need to print left and right twice. circuit side down,
you can add a filament change like it did for added coolness.
You'll also need to print the blade twice, once mirrored.
(Check out the .gcode files if needed)
you'll need to acquire 26x m3 nuts and 4x m3x12 socket cap screws total:
6x m3 nuts for the blade (insert and glue the blade halves together)
16x m3 nuts for the handle weights.
4x m3 nuts and 4x m3x12 button head screws to assemble.
blue locktite is a suggested, but not required.
Enjoy!
The author remixed this model.
hid the nuts in the handle and the blade, made the blade a tanto, and added circuit board engraving to the handle.
