 Using low-tack "removable" sticky tape can make it easier to swap round and reuse the rotors if you want to do that, but it's not essential.

This includes the neat feature of using the tube cap as the reflector.

-The final component that we need to be fully compatible with a real German army Enigma machine is the plug board.  The German military added this when they adapted the commercial version of the Enigma machine for their own use, and it improves the security a lot.  Twenty-six sockets on the front of the machine (one for each letter) can be connected together in pairs with jumper cables.  If a letter has no connection to it, it passes through unchanged.  Any two letters connected together swap with each other before being passed through the machine and then swap back again for output.  There were different numbers of connections used at different times, but the later standard was ten.

 To represent this in our model, we need to write in the jumpered letters on our input/output cylinder.  If you use a pencil, you can rub them out afterwards and reuse the cylinder (it helps if you used matte-finish sticky tape, as that's easy to write on and rub out).  For each letter that is jumpered, write the paired letter in next to it.  For example, if D and Q are paired, write D next to Q, and Q next to D.  Do this for all the jumpered pairs, and then for the rest of the letters which have no plugs in, write the letter next to itself.

-Note that the rings for rotors II, III, IV and V are printed in two parts due to lack of space on the page; you may find it easiest to tape the two halves together as a block (so the letter N on each ring joins on to letter M on its other half) before separating the individual rings.

 Keeping the rotors I, II and III that you put on for the basic machine, put rings I, II and III over the top of the letters on the rotors.  Just tape the ring to itself so it can still move over the top of the rotor; and make it snug so it stays in the same place relative to the rotor when the rotor is turned.

		+	* Use 3 colours for rotor wiring to make parallel lines easier to follow
		+	* Reduce size of input / output cylinder to fit on shorter 165g crisp tube
		+	* Rearrange templates so they can be also be printed on US Letter paper
