The Servo-Launcher (that's it's name, see: http://www.ninfinger.org/rockets/no...a/72cen052.html ) would make an excellent 3D printed "Retro-Repro" piece of GSE (Ground Support Equipment). Having a pneumatically-activated ignition switch on the pad itself (it had no ignition lead wires), its batteries-to-igniter wire leads were only a few inches long (and thus had very little voltage drop), which enabled it to fire igniters using only two Photo-Flash "D" batteries. (Today's alkaline and rechargeable "D" batteries would work well, too, and connecting two more into the circuit might be ample for igniting clustered motors.)
