Mechnical Laser Light Show Better Gears

I could never get the gears to latch satisfactorily onto the cams and when I did there was always friction between the gears.

this remix cuts a square keyway into the cams and makes a square key on the end of the gears.

The gears are also spaced better away from each other and the friction is reduced by the addition of washers.

I've only modified the bat cams as these are the only ones I wanted.

Kudos to original designer AdditiveTech.
