    Step 1: Insert the screws through one thigh

    Since I use the round-head M3 screws (5.5mm head), it sinks through the hole on the thigh plate. So I use two washers.

    Tips: Here I use some acrylic washers. If you don't have these, you can make them with a thick cardboard or cuttable plastic board [2]. Then cut the board based on the holes' size on the thigh and the keys.

    Step 2: Put a key on one screw and a wash on the other

    It doesn't matter whether to put which on which. But remember the washer should be almost as thick as the key.
