Plywood – 4 mm (remember to measure the wood thickness, my plywood ended up being 4.2 mm!)
Secure the plywood to the waste-board.

Assemble by slotting the two pieces together. The fit ought to be loose, as there needs to be some play for the stand to lean backwards. The groove-slots can be carved more narrow if you would like the stand to be more upright.
If you would like to jazz the build up a bit – you can use the following link:
