I'll do STL, since i can readily convert it to.It's nice of you to do this, but could you load them in a slightly less obtuse format? .Dxf, .Dwg, .obj, .stl; or something that is otherwise industry-standard?
The slanted teeth on the lug is for a problem some of the first printed turrets I made, where the sharpness of the lug teeth would cause it to chip away the top layer.It looks like the teeth are slanted so that there will be a gap between them on the inside, but not on the outside. Why is that?
