When Hoplite Industries needed some overpriced spacers, I was able to 3D print some suitable alternatives for a fraction of the cost using OpenJSCAD! Watch my talk at Big Sky Dev Con in which I talk about making real things using code.
I've read that dowel joints are nearly if not as strong as mortise and tenon joints. The mortise and tenon joint requires expensive tools (specifically a table saw and a router) and the know how to make them, but dowel joints can be made with just a drill. The tricky part, though, is getting your dowel holes lined up on each piece. With my dowel jig widget, you can configure a jig for your specific situation and 3D print it at home or for an affordable price online.
I designed and 3D printed a gear shifter for my car. An engineer experienced with direct metal laser sintering wanted to to make his own out of titanium. In exchange for the model, he made me one as well. Read about how I barely managed to tap threads into it and see how you can do it yourself in a stainless steel version.
Using my knot software, I've created all kinds of knots. I've tied them myself, 3D printed them, and CNCed their patterns into knot mandrels. In this post, I show you how I used wooden dowels and 3D printed connectors to assemble a knot that forms a globe and has no beginning or end.
See how I modified my workbench to hold all my filament directly above my 3D printer for convenient storage and easy swapping.
Create your own mouse wheel using a rotary encoder, then use it as a jog wheel for the Pocket NC.
I show you how I fixed a stubborn 3D model by converting it to a voxel format and back to a mesh.
