Amiga "Pregnant" Mouse (Two & Three Button Variants)

thingiverse

This design is the two and three button versions of the Amiga "pregnant" mouse. I didn't model the cord, but did do the plug. I made it only from pictures I found online, which required a lot of guesswork, so I'd be most grateful if someone who owns one would be willing to give me some measurements (or, better yet, if they'd scan it!). I may eventually 3D print one and put some modern mouse guts into it (have to think about how a mouse wheel would best be integrated...).
