D-Cell conductive dummy

In case, a device that requires an odd number (e.g. 3 or 5) of D-Cell batteries should be powered with the https://www.thingiverse.com/thing:4798701 18650 Lithium adapter, this conductive dummy ensures, that the Lithium adapter fits into the battery compartment and makes connection on both sides.

Assembly: Print the body of the conductive dummy and screw in a 58mm M6 threaded rod.On the bottom, the thread should stick out just a little to make connection with the coin. Insert a 2 Euro-Ct coin on the bottom of the adapter that will serve as the connection to the springs inside the battery compartment. If assembled correctly, the metal tip on top of the adapter should have connection with the coin on the bottom (Check with an Ohm meter and screw the threaded rod a little more towards the coin if the adapter doesnt work)
