It may be worth noting at this point that the batteries are only 38ma/hr, using them in parallel will give around 120ma, they will not last long, but long enough to be usable. You could adapt this for a lava drive which will make better use of the batteries, I had a Rkcstr so I used it.

Cut a piece of 8mm X 0.5mm brass 25mm long, file a corner off and solder a piece of wire to one end as shown.
The Rkcstr drive can now be attached to the insulator with a dab of glue, place it with solder pads for the laser diode upermost and toward the wires.

Bend 3 wires as shown, trim them to length and solder to correct pads on the driver. Push loops into the remaing holes in the insulator and glue in place. The wires will be perfectly positioned to pass through the drilled out holes in the veroboard.

Connect the wires as shown, leave 4 long ends sticking up, these will be trimmed later.
