Here’s a nice new plugin for Fusion 360, by Autodesk themselves. It’s called Slicer, but it’s not the 3D printer type of slicer; it’s actually better suited for laser cutters (and CNC routers)!
It gives you a bunch of options in how to slice multiple layers of cardboard, plywood, etc, and produces the 2D maps for cutting out everything.
This video explains it a lot better than I do: https://www.youtube.com/watch?v=4fFH_TcI-9U
Looking forward to building some cool interlocking models with this!
