Sand and paint as desired.

Hot glue your magnet into the hole.

If hole is too small to accept a magnet, additional drilling may be necessary to expand it.

Make sure the polarity matches with magnet installed in the mouse!

Magnets must be installed 14 to 20 mm of the lens.

Install a total of 4 magnets, one directly above, below, left and right of the lens.

Make sure the polarity matches with the magnet installed in the knob!

Ensure that the magnet does not interfere with the proper functioning of the mouse, and that no electrical components are shorted.
