Here is Hovus, a box articulated in 12 parts on the principle of the sarrus linkage mechanism.
This box was created by me on solidworks. For now it remains a design object, but you can find a use for it without problems (like making a lamp, adding an engine or many others). The dimensions of the box allow you to hold a can of soda inside.
The parts are of a simple design, and there are only 4 different models for the whole box.
The full print uses 145 grams of material. It will cost you around 3€.
Be sure to print 1 top, 1 bottom, 10 sides and 15 axes, otherwise the mechanism will not work.
The pins do not have axial locking to simplify printing, be sure to glue the pins in the full top and bottom parts once you do the assembly.
