Ergonomic handle grip and slider knob. 2 spring strength options. Blade modified for printing in PETG. 

I've uploaded profiles for PETG, but the grip and slider spring should still work in PLA. The only one that might have issues in PLA is the blade, so you might want to use the original model's blade instead.

Remix of several parts from multiple creators:
- Discobanan's “Comfy OTF Fidget Knife” handle exterior, combined with the Handle (Guided Version) interior from uhltimate's original OTF Fidget Knife. The comfy handle had slightly modified internal geometry and I found that the original handle functioned better mechanically.

- LucasAlexander's “Ergonomic slider for OTF fidget knife” thumb knob, combined with the uhltimate's original Slider with Strong Spring
- I remixed uhltimate's original Guided Blade by making the hook arms at the bottom of the blade thicker. When printed in the more flexible PETG, the arms from the original model would bend under the weight of the slider spring and cause the hooks to release too soon.

2 plates: one with the original ergonomic slider and one with stronger springs. The stronger springs require more effort from the user in order to activate, but transfer more force to the blade. So if your blade isn't sliding all the way up or down properly after the spring releases, you can try using the version with stronger springs.
