Hingesmith vs boxes.py

The open-source generator for finger-joint boxes, trays, shelves and dozens of other laser-cut objects. Here is what each does, so you pick the right one for the box in front of you.

What boxes.py is

boxes.py is free, open-source (GPL) software by Florian Festi, started in 2012. It runs as a web app, from the command line and as an Inkscape extension, and generates finger-joint boxes, drawers, trays, racks, gears and many special-purpose objects. Its FlexBox generators make rectangular boxes with living-hinge corners and a burn (kerf) setting; its defaults are the field-proven numbers Hingesmith’s strain limit was calibrated against.

Best for: Rectangular finger-joint boxes of every kind, and makers who want to script or extend a generator.

What Hingesmith is

A generator for the boxes a finger-joint tool can’t make: 100 curved outlines whose wall is one strip of plywood with a living hinge. The cut spacing is solved from the curvature at every point of the wall and the wood’s twist limit, alternate cuts run out through the edges, and you watch the box fold together in 3D before cutting. Three shapes and two hinges export free; Pro unlocks the rest, custom kerf and DXF.

Best for: gift, keepsake and seasonal boxes with a shape, and any box with curved walls.
