nuts template

thingiverse

When designing things, we very often need to add holes of special shape (for nuts, rods, bolts). In OpenSCAD we use command cylinder( ... , $fn=3,4,5,6,...) i.e. we draw a cylinder with small amount of facets. usually, to pick up appropriate size for a nut, I have to print the part, try to apply the nut and then correct my scad design. To avoid this, I designed this stencil.
