About this 3D model

When the control stick broke on the A-SCAN at the Eye Surgery center I work at, I as the repair tech was called down to see what I could do to fix it, The original stick had snapped at the base. There is a button in the middle.I called everyone I could think of to get a replacement. No luck everyone told me there are no replacements available! I need to buy a new or referbished machine! - New ones are $20k and referbished are a few thousand. So I decided it was a good use for the 3D printer I have at home. I took the machine appart, removed the part its attached to and took it home on a friday. When we opened on Monday the machine had the 3D printed replacement and everyone thought I bought it! Its stronger then the original and its been going non-stop for at least a year! I saved the company a bunch of money and I used my printer to make something that was more then usefull...
