Full size, 3D printable synch generator 'details' of the Ghostbusters' proton pack based on Steffan Otto's plans at: http://www.gbfans.com/wiki/Stefan_Otto%27s_Prop_Plans Use in conjunction with: http://www.thingiverse.com/thing:526328 Epoxy parts to the outside edge of the synch generator. If you feel the SG walls are too thin, print the SynDetlButtress.stl, and use #4 screws to fasten the flanges of the SG plates together, instead of bolts. Epoxy the bottom and outward facing faces of the buttress to the inside wall of the synch generator.
