This box is composed by differents parts which have been cutting with a laser machine (Epilog Laser Mini 40w) and after that they joined between them with a system of hooking which I'm going to explain in the step of design.
The materials are differents types of 4mm depth wood. I divided the box in 8 diferents parts, two laterals, the front, back, the base, the top and two inside walls in order to get three comparments.
The machine is the Epilog Laser mini of 40w
Step 1: Design
I worked with the software AutoCAD. The mesures are in milimeters 180x80x4 (length x width x height).
The most important part of the design is the diferent fixing elements.
They should have the same height that the height of the wooden piece of the base which is 4 mm. This is easy, but the dificult part is the width because it can't be equal as the hold in the base for each fix because like we are cutting with the laser machine, it burns a little part of the material, in my case, it was 0.5mm per hold, so I should add to the width of the fixing element. Everything is called the tolerance.
The other important measure that we should take carefully was the distance between the lines on the top which are going to be cut for achiving the flexibility on the top. The distance between them is nearly 1mm vertically, and the horizontal space is 11.25mm. With this measure we have succeed and it works perfectly
Every fixing elements, which are hooking in the base, were in the middle of the part which they hook because I tried to make the box as more symmetrical as posibble.
The fixing elements for the top are hooking in the laterals, the hold for them are circular and the diameter are a the same of the width of flange in the top thus the machine is going to burn the tolerance so it can rotate with freedom.
