Once I designed a machine, I need a case to put it all in.<p>
Time to build a big box.<p>
The design of the case / box only had one big requirment, the keys / buttons need to be at a distance such that one person can’t turn both keys.<p>
Plywood comes in 2.4 meter sheets, so a box that is 2.4m long was easy.
Cutting up plywood was nothing fancy, a stright edge and a skillsaw.
Add some holes for keys and override buttons, then it’s just a case of nailing to box togeather and adding some paint.
