Earlier, we had a set that included our 3d-printed signature punching tool and four corner cutting jigs of different sizes (1.5 mm, 2 mm, 2.5 mm, and 3 mm). We decided to extend this set and included four corner clamps for boxmaking. Guides for the punching tools have their holes numbered, and the numbers are printed in a contrasting color for better visibility. We received multiple reviews from our customers mentioning that this is very helpful, especially for people with impaired vision.
