folding workplace

I needed an extra workspace at my workplace. But I did not want to have them all the time. So a foldable version had to arise. The plate can be unhooked at any time!

I use a 6mm thick pice of waterproof plate from the hardware store 650x400x6cm
1x srew M10x80 with M10 nut
1x washer for M10 with 30mm !!! outer dimension for the hinge
some M4 screws with nuts, some wooden screws and M3x20 countersunk screw with nut

The wooden stand is a plank which lays around in a corner. For my table height 700x300x19,5mm
