This is my take on the brilliantly designed OTF Fidget knife by Uhltimate.
I reversed engineered the files and made some mods. Only 5 printed parts, no hardware, a single drop of glue and two small sections of filament.
Tell me what you think.
Changes are:
- 75 deg hook angle for better blade retention and click action.
- an exterior shell to minimize finger & palm drag on spring.
- a flat face thumb slide for easier deployment and pocket-ability.
- easy glue thumb tab (no hardware)
- use of snap fit for outer shell retention and/or filament as hot swaged pins for permanent fixation.
Suggested to use stiffer filament for main body (PLA or CF-ABS) and something with a bit of give for the outer shell (PETG).
Use a single drop of glue to affix the thumb tab in the slot. I printed mine in ABS so I used acetone to weld it.
If you use the filament sections to hold everything together, just ream out the holes with a 2mm drill bit and heat a small metal object to splay out the ends of the filament making them into plastic rivets. Works great.
If you just want my outer shell design for the original uhltimate knife go here:
