Joinery – Not just for lasercutters any more
The Make Blog recent posted about CNC panel joinery techniques. However, there’s no reason these really amazing assembly techniques should be relegated to just CNC cutting machines. Any of these techniques could be easily applied to 3D printing to create objects that can be assembled without any tools or hardware. Some of my favorite things to 3D print of all time are multi-part pieces that can be hand assembled. There’s the dinosaur, the spider, the 27-to-1 gear ratio crank, and Tony Buser’s Toy Robot Toolkit.
Of course, having a 3D printer at your disposal means you don’t need to use joinery to create a 90 degree angle or a corner like those pictured above. Even so, there’s no reason why one couldn’t use those same techniques to connect larger, more complex, 3D parts. I would love to see an OpenSCAD library of joinery – little cutouts and tabs that could just be dropped into a design to make it snap-slide-slot together.
