gluhzunder 28 (copper)

This uses the terminal from https://www.printables.com/model/173169-10-cap-blasting-machine/files. credit to him.

This is the early war version of the gluhzunder 28 which would be made of copper with slightly different dimensions from the bakelite version. Other wise the functionality is the same.

This would contain the detonator and be threaded into the explosive. The electrical wires or timed fuse would run through the opening in the cap.
