This is a remixed version of https://www.printables.com/model/173169-10-cap-blasting-machineAll the credit goes to him for the inspiration. This is the German blasting machine (Gluhzundapparat 40) used in WWII for demolitions.Most of the parts from the original version are compatible with this. The biggest difference is that this is used for reenacting and made to contain a 9 volt battery + metal bolts to have the machine functional. If using as a display piece, use the same bolts and terminals in the original version. To convert to a functional machine, you'll also need:9 volt battery9 volt connectorelectrical tape1/4" x 3" carriage bolt2 1/4" nuts5/16" x 1.5" bolt5/16" x 3" carriage bolt5 5/16" nuts18 gauge primary wire2 16/14 AWG ring terminals16/14 AWG butt connector2 4mm x 30mm bolts2 4mm nutswrap one layer of electrical tape about 1.5" long from the bolt head around the 1/4" bolt and feed through the hold at the bottom of the plunger.Place the 9 volt battery inside the well in the body, connect the connector.strip the end of the red connector and connect with the primary wire using the butt connector (this is to give it some extra reach)crimp one ring terminal onto the primary wirethread one nut all the way to the end of the electrical tape, place the connected ring terminal through, and then sandwich it with another 1/4" nut.cut off the top half of the other ring terminal and crimp to the red wirethread one nut all the way to the end of the shorter 5/16 bolt and sandwich the cut ring terminal between the bolt head and the nutfeed both 5/16" bolts into the top cover upside down, but have the 3" bolt about halfway through, or inline with the shorter one.finger tighten 2 5/16 nuts to the top to hold the nuts in place.assemble and use the 4mm nuts to secure the top cover to the body connectorTest by connecting a christmas bulb or a volt tester to the terminals, there should be no current until the plunger is rotated and the 1/4" bolt touches the long 5/16" bolt.if there is, check the electrical tape and make sure it fully covers the bolt. Plastic conducts electricity, so if the tape is not covering everything, then some current is flowing throughout the body.
