Z-11 blade key-chain knife

Update 7/14/2019

Just uploaded an improved version that moves the slider window over the cover instead of the body which makes it feel more solid. I also enlarged the key-ring hole.

I wanted a small holder for a hobby z-11 blade that I could attach to a key-chain so I designed and made this.

it requires 2 items

• Standard Z-11 hobby blade
• Small screw (or something similar in size although you can just superglue it together if you dont have a small screw)

and 3 printed parts (body, cover and slider)

It is non-locking, but it has a detent to keep it open or closed and this also allows it to have a decent fidget factor allowing you the flick it open with your thumb nail.

Different Z-11 blades have slightly different dimensions so you may need to shave down some of the slider to wedge the blade in properly (or use glue)

I recommend printing as shown in the cura screenshot.
