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).
Cheers,
Peter

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.
