As you can see for the above picture the case made for this Mastermind game by Attache has the perfect side needed for this project.
The game comes fixed to the case in the way shown in the next picture:
It was very easy for me to cut with a Garden Scissor the plastic bar that kept the plastic board attached to the case.
The last picture shows the game in the way it was packed by its maker.
The game can be found at Amazon for 14 dollars.
