Manual 123D system
thingiverse
After the announcement that Autodesk is to end 123d design, I decided to create a manual version of the software. Just print out the stock basic primitive shapes provided by 123D Design, then you have all you need to design any manner of STL. The STL file attached contains the Assortment of Primitive Reference Images for Layout. You'd be a fool not to take advantage of them before it's too late.
