Folding Knife (Multi-tool)

[please watch the video at the end of the description for an overview of how the knife operates, and assembly instructions]

[I will also be uploading a model that is a thinner version with belt clip and keychain options - check my profile]

UPDATE:  January 23rd, 2025

I have included a new variation of the model that uses a metal rivet as the center pivot. This adds a substantial amount of strength to the knife, as the 3d-printed pivot is the weakest part of the knife. See pictures in the Print Profile provided.

______________________________________________________________________________

Please use the print profile(s) I have provided - I have tweaked it quite a bit to create the strongest and best print for this model (using 0.4 nozzle & 0.2 layer height). If you use your own print settings, I can't promise it'll print nicely.

This knife should be printed in PETG. PETG has better layer adhesion than PLA, which increases the strength, and also more flexibility which is important for the operation of the wings, and the blade spring. I have provided a PLA profile (which is exactly the same but with looser tolerances), but a knife printed in PLA will not operate quite as nicely. Do not use the PETG profile when printing with PLA, as the tolerances will be too tight (PETG shrinks more than PLA and I have compensated for that). If printing in PETG and tolerances are too tight, try printing the PLA profile (with PETG).  And Vice Versa…if printing with PLA, and the profile is too loose, try the PETG profile. 

Version 4.0 updates (compated to Version 3.0)

1. Thicker for better ergonomics
2. Tool-less blade changes
3. A new pivot/locking mechanism that allows for beefier and stronger parts, which creates a stronger knife. 
4. A ruler (Metric and Imperial)
5. An angle finder (45°, 90°, and 135°) 
6. A screwdriver (4mm bits) and storage for two bits

Special Notes

1. This is a plastic, 3D printed knife. Please use with caution. Light duty applications only. It's pretty strong, but it's still not a metal knife.
2. Use THICK Superglue (CA Glue) for the assembly (You can use thin, but it's much harder, and you risk weakening the knife)
3. 2x6mm Magnets are optional, and the knife can operate without them.  However, some of the features require them.
4. PLEASE make sure you let your print bed completely cool down before removing the parts, so there is less part warping.
5. The weakest part of this knife is when you pull apart the wings to open it. Pull it apart gently, and only enough to open it.
6. All knife parts can be downloaded individually as STLs.
