Since I didn't like any of the other designs of this iconic prop, either for being inaccurate or requiring screws to assemble, I designed my own, fully 3D printable version. It's the most accurate replica of this worldwide-known knife from the game CS:GO and feels very solid in hand.
It can be printed on any machine because the multi-color version is printed with just a filament change, no dual-color printer needed.
It moves very smoothly (as far as 3D printed butterfly knives go) so tricks can be performed quite nicely. The blade can be printed in two parts and glued together afterward (but with a seam along the middle), or in one part with no seam (but I'm not sure what the best model orientation would be since the blade is too steep to be printed on its side, but you do you).
There are 3 ways of printing the handles:
1 - with an automated filament change in Cura (which doesn't work on all printers, including mine)
2 - as two separate gcode files (as I did), one of which is 5 mm above the print surface and printed on top of the handle (manual positioning of the models required since the handle and the padding don't have the same center point)
3 - as two completely separate models glued together (not as strong)
Share and like if you like this model.
Read the print settings and assembly notes below.
WARNING: Just in case somebody would be very dumb and wanted to use this as a weapon, I want everybody to know that this is just a replica for display or trick performing and wasn't by any means designed as a weapon.
I also want to say that I have no profit from this, so, please, don't sell it as your design. You can sell printed copies of this as long as you link to this model tho. Thank you.
Printer:
JGAurora A5
Rafts:
Doesn't Matter
Supports:
No
Resolution:
Blade at least 0.16, for other files, 0.2 is enough
Infill:
100% (for better weight distribution)
Filament: doesn't matter PLA Two contrast colors
Notes:
A brim is recommended since the parts are long and prone to warping (believe me, 5 mins of clean-up are better than having to re-print the whole part).
Assembly
Glue the blade together.
To assemble, just take the left bottom handle, connect it with the right bottom handle via the pins and pin ends and put the spacer between them. Repeat for the top handle (if needed, use a hammer to slide the pin ends over the pins, but be careful). Then, take the end stop pins and insert them into the very front and very back hole on the blade end. Slide the bottom handle over the corresponding hole in the blade and use the pin and the pin end to secure it in place (again, a hammer might help but mind your fingers and your part). And that's it! You're ready to do some tricks!
