Lock Pick Short/Medium/Long Hook

Functional lock picks with robustified hook design.
 

1mm or 0.7 mm hook thickness

Short hook is more rigid and functions better than Medium hook.

Print with 5 walls/100% infill

Use stiffer materials such as PLA, PLA-CF. 

ABS or PETG are more flexible which is bad for printed lock picks.
