Knife Saya (sheath) PARAMETRIC

PARAMETRIC knife saya (sheath)

Sorry there are many configuration parameters and they are a little confusing. Please see the comments when modifying the parameters. You can get a sense with what all of them do if you play around a little. IMPORTANT  “ratio” parameters must be between 0.01 and 0.99 or the model may break. 

Here is a diagram that helps explain some of the parameters:

The f3d has a second model in it that is the internal “hole” shape of the saya which you can place your knife against the monitor to see if you got the shape about right. It's better the hole be too big rather than too small! Once you download the model into the slicer, use “split objects” feature to separate out the “hole” object and delete it.

The f3d is available [here on github](https://github.com/minimapletinytools/3dpoops/blob/main/random/KNIFE_SAYA_PARAMETRIC.f3d) as well.
