Was looking for a model to expose my pocket knives, and found one that looked good but I thought it used a lot of filament, and also it required the knives to be exposed open which wasn't what I wanted.
Did a small edit of it, and removed as much as I thought I could while still keeping it sturdy enough.
I have an optional STL with little ridges to hold the knives, because one of mine did tent to slip from the holder.
