This is a pololu regulator case that I modeled for my FRC team. The programming team needed one so that the pololu regulator wouldn't be damaged during competition. To mount the pololu regulator itself, you would have to used 2mm screws with 2mm brass inserts. To attach the cases (top and bottom), you would have to use 8-32 bolts and nylock nuts. I have uploaded a file that shows the assemby :) You certainly don't have to use it specifically for this, but the dimensions might be different. You can remodel it based on your preferences and make a remix!
