    Re: Mirror adjustment tools

    Hi Hien,

    For driving your square-head adjustment screw, maybe a tool can be improvised.  Try taking a piece of metal tubing and crushing the end of it into a square shape with needle-nosed pliers.  For a low-torque application like this, it might be enough for temporary use.  Alternatively, you could take a piece of steel rod (that will fit within the circular shell) and file a slot into the end with a Swiss needle file.  Naturally, this will grab the square head on only two sides, but again it might be enough.

    I agree with Frank's comment about 3D printing offhand custom tools like this.  Some plastics might be adequate, or one could go with a printed aluminum part from the service bureaus for not very much money (maybe $15 for a small part like this).  Or use a home printer to make a mold for casting low-temperature alloy (tin or tin-bismuth).
