Diving deeper into the world of CNC: creating hidden joints

As we needed a box to keep all the sand casting stuff in, i designed and produced this box. The special thing about this is that the joints are hidden between the interlocking edges of the box.

The box was designed in fusion 360.

Then milled on the shopbot. The shopbot is extremely precicise, it all came together with a few blows with the hammer here and there.

A closeup of the joint halfway in the assembly proces.

A very clean interior is the result of the hidden joint method.

I used this strap to keep together under the assebly process.

This is the box filled with sand. The lid is handy for keeping the sand dry.
