This is a case for ICStation's step-up module. The design features a hole in the side to allow easy access to the potentiometer that sets up the output voltage.

I'm currently working in a project that uses this module, and I designed a case for it in order to avoid any accidents that might arise if the exposed PCB makes contact with a conductive surface. I thought it would be a good idea to share it, as it might be useful for Makers who have this module.
