Custom Feature: Friction fit (interference fit) quick sketch tool

I started adding a small ridge or notch in items that I need to fit together snugly but where I don't trust the tolerance of my printer. I found it tedious to manually sketch 2-4 small ridges to extrude up the side of every box, so I have created a feature studio that does this automatically, adding a sketch to the centre of every edge of a selected face.

I'm a hobbyist so I've written it with assistance but I've spent quite a lot of time checking everything works as it should and is easy to use.

I would quite like to upgrade it to allow extrusion of the sketches in the same tool, but I couldn't figure out how to get the extrusion menu as rich as the native extrude UI, so I figured I would just do it manually.

    Updated to version 7 - now adds "exclude" box which allows specific edges on a face to be deselected.

    This looks pretty useful, I'll add it to my collection. I'm kind of a hack when it comes to printing so I'll take all the help I can get.

    I'm not doing much indoor stuff this time of year but sooner or later I'll give it a try. Thanks!
