A case to compose spare parts I had into a laser pointer

Parts:

• some random button I had (sorry I don't know its details)
• some random laser element I had (sorry I don't know its details)
• a standard two AAA battery case with sliding top and power switch

Assembly

Solder everything first.

The button snaps in.

Glue the top of the battery case in so the bottom with the batteries in it can slide out and the batteries can be replaced.

Glue the laser assembly in.
