Equerre
thingiverse
A square! Here's one of the objects I've modeled, and it has been a big help to me. Since I got my 3D printer, I've dreamed of making my own storage boxes, and today that dream is a reality thanks to these squares. These squares can only be used with boards made of 18mm thick wood, but soon you'll have access to all the sizes and types of squares I've modeled.
