Knife sheath

thingiverse

I bought a kitchen knife from DAISO, but it doesn't go with sheath. To make it safer at storage, I decided to print a sheath for it. After searching Thingiverse, I cannot found any model fitting this knife, so I use Fusion 360 to design one. I first took a picture of this knife and set it to the canvas layer in Fusion 360. I sketched its blade with special curvature. However, my first work cannot fit the knife well because of the spherical aberration. The uploaded file is the 2nd version of this knife sheath, they fit perfectly. I also add a logo of my workshop.
