WWII German blasting machine

This is a remixed version of https://www.printables.com/model/173169-10-cap-blasting-machine
All 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 battery
9 volt connector
electrical tape
1/4" x 3" carriage bolt
2 1/4" nuts
5/16" x 1.5" bolt
5/16" x 3" carriage bolt
5 5/16" nuts
18 gauge primary wire
2 16/14 AWG ring terminals
16/14 AWG butt connector
2 4mm x 30mm bolts
2 4mm nuts

- wrap 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.
