The wheel can be found easily from Mouser or Digikey.  The laser
may be more of a problem, if you want visible.  Plus, laser diodes
are EXTREMELY static sensitive (no really)(really really really).

To give an idea, just transferring laser diodes from one static proof
container to another, with wriststrap, heel strap, at a grounded
bench in a static smock on a static safe chair dragging a chain on
a conductive surface floor, I still managed to kill 3 of 30.
