The other modules we linked you make a dot, not a cross.
Just search a bit for yourself on that site, then order half a dozen different modules,
wait for 3~4 weeks and then just go crazy.
All these modules need to shine is those 4~5 volts on those wires.
Your question is not really about lasers, since that module is already a complete "package".
Your asking a fabrication question, isn't there a "monster-garage" forum for that kind of stuff?
"Bolts" are not a very popular choice of host around here.
