I printed the Modular Pedal Board, the problem is that the volume or wah pedals are in angle and it is difficult to use them, mainly when you have to bring them up. 

So I disigned a riser that can be used for pedals that you want to use parallel to the floor. It is pretty simple but the idea is that it can be scale in one direction depending on the width of the pedal. 

You can slide it before installing the foot of the board. Once installed it doesn't move, even when using the pedal.
