Ikea Bissa baby proof

I use the Ikea Bissa shoe rack to store my game consoles next to my TV. This is to prevent my son from opening it. You will need:

• this printed part
• some spacers for the bottom parts. Sorry i lost the model i printed, but it is basically an extruded rectangle with holes that you can generate from the provided Fusion 360 model. Maybe simple cardboard can do the trick
• an 8mm rod
• some screws
