Atari ST Optical Mouse

This is an optical version of the Atari STM1 Mouse that came with Atari ST computers. The intention for this was to use with a USB/ST mouse port adaptor (linked below) for an Atari ST as I did not want to use the original ball mouse, but I wanted to keep the period look when using the ST.

I designed this in FreeCAD using measurements from the original mouse as a basis. It is not completely identical but in terms of aesthetics, it is fairly close.

EDIT: the reason I chose the mice below as donors is because they were the only ones I could find that were compatible with the following adaptor for use with the Atari ST:

I have tested both mice donors below with the adaptor linked and both should work on an Atari ST.
