I made this angled mirror holder to allow easier viewing of LED indicator lights on the underside of a PCB. This is useful when I have the PCB fixtured upside down in order to access test points on the opposite side of the board.
If the pin isn't tight enough in the holes, you can heat up one of the axle holders on the base with a heat gun and give the plastic a little squish. This will stop the mirror from flopping around too easily.
