Knife Sheath - Sew/Glue together
This was really designed to superglue together and then sew a stiching for effect and added strength.
Using Cura as a slicer
The spacers can be scaled up or down in thickness based on you knife bade thickness
The Bottom/inside piece has two options a DYI attachment or a Bladetek - Tek-Lok style mount.
This was designed to fit a variety of knives that range from Extrema Ratio, Fallkniven and even a random 7-inch Kukri. Seems to hold together well. The design is modification of my Machete sheath.
