The only thing worth doing, is the thing worth doing right!

This idea came about from the tray mechanism of a CD-ROM drive, I liked the screw idea it has for the lateral movement controlled by the little stepper motor, so I took a "sneek peek," inside a product from Thorlabs using the reverse engineering feature from FreeCad.

I have been thinking about this concept for months now but couldn't figure out how to make it work effectively, and cost effectively, so I merged both idea's from thorlabs and the CD-ROM drive and came up with this design and theoretically it should work. I built a very crude model and it does work (with some minor problems,) but it does work, so I went ahead and designed this model with as much precision as possible.

Even for 3-D printing this might be pushing the envelope, but if this works, it will be a beautiful thing! So before uploading any STL files for this, I am going to get the parts printed and assemble and test it, to validate it's operation and hopefully its success.
