Similar projects worth following
i have been thinking of making a small portable 3d printer
it will need: 4 cd/dvd drives, 3d printer driver board, batteries, more stuff
i have not started this because i have no money to buy parts
once i do make it, if it works well i will make a kickstarter campaign to make and sell kits.
it will print in high quality since the stepper motors for the sleds are designed to move lasers accurately
comment your ideas for this

Enjoy this project?

All the CD sleds I've seen are DC drive, not steppers. It appears that the lens is moved with a "voice coil" for precision tracking. I don't have much experience with them though.
