Fillet knife sheath

I wanted a safe way to carry the Victorinox 5.6663.15 "boning" filleting knife since it does not come with a sheath and I am always carrying it along with a bunch of other fish cleaning stuff. I wanted something with holes for easier cleaning/rinsing after use.

It would likely also fit the 5.6603.15 and other Victorinox 6" curved blade knives like SWIBO versions.

STL file for viewing purposes, it's better to print the STEP, though it's not a complex model.

Any filament should work, I used ABS, but PA6 would be optimal for a little bit more flex whilst still being strong, same with PETG. PLA or anything brittle the handle clip would need beefing up I think.

STEP file is there for you to mod that clip.

I purposely printed it laying flat as I expected the bridging droop to make the knife snug and it is indeed, with little need for the clip. I also added a brim and some small manual tree supports to the clip area as ABS is prone to warp when printed so thin. See included slicer preview example. 

I did consider putting hidden magnets in it but mine came out quite snug so it probably isn't needed.   

I allowed approximately 1.5mm clearance for the blade in X-Y, and a blade thickness of 1.8mm which is not tapered. Please consider that when scaling.
