Nixie Tube (rev B)

Updated the previous model with complete number sets, additional internal components & mounting plate. Todo: figure out how to position the numbers in XY to handle obscuring in a frontal view, maybe reduce the size of the internal bits so that the number spacers don't intersect the glass housing (ooops), add labeling to the glass. I almost wish I could do this (3D modeling & rendering) for a living...
