motors / headers

hi all,

sorry, i am wondering about motors and would like to gain some experience
with them.

does anybody have some spare motors (dc, stepper, servo) which i could
borrow for a short time, please?
also, which kind of motors are in the 3d printer or laser cutter? (are
these stepper motors?)

does anybody have a disk drive or old cd drive flying around and does not
need it anymore or could lend it to me, please?

does also anybody know the farnell order number of long (approx 20 mm)
straight break-away header pins? i tried to find them and failed miserably.

thanks for the help and greetings from darmstadt, germany.
