3-D Printed cutting guide for trimming stringer ends.
Triming the stringer ends is always a bit difficult. Ideally, they are trimmed so that the angled cut allows the end of the stringer lays flat onthe side of the stem. They have to be short enough not to extend past the stem, but not so short that they can be lashed to the stem. The sharp angle means that a small error left or right can significantly change the 'landing' point of the stringer.
