Carpy

Dog-Bone Generator

Router bits can't cut sharp inside corners. Upload any SVG cut file, pick your bit, and download it back with dog-bone reliefs added exactly where they're needed — so your joints actually fit.

Optional safety check: your stock should be at least 1 mm thicker than the bit — thinner than that, the reliefs devour the joint. Enter your thickness and Carpy enforces it.
Reliefs are cut 25% larger than the bit, so the bit enters cleanly and joints don't bind.
Your file appears here — every interior corner gets its relief automatically.
