Step 4Presto! Away you go....
Hope this has been helpful.
************** UPDATE ******************
I have found a way to add a AA battery instead of a AAA (Note: These batteries are rechargeable and this is important to the voltage for this LED).
1. Using the Hobby Rotary Tool, the tips will allow you to "burr" out the plastic that is in the way.
Burr it down as far as you can reach with the tools. Leave about 1.5cm from then end still in tact.
2. Pull apart one of the battery comartments you bought from DSE...specifically this one. pull the end apart removing the switch and the two terminals from the same end. Keep the wires attached (see image below).
3. Using the Hobby Rotary tool again, bur a hole just large enough to fit the witch into. It doesn't matter that the switch hangs over the plastic. You want it this way so it doesn't fall into the tube!
4. Cut out a circle, slightly larger than the clear plastic tube using the Hobby Rotary Tool. Now you want to make this fit inside the clear tubing with a small gap on at least one of the side so you can push the wiring down beside it.
5. Once this is done, solder a short wire onto the terminal with the spring on it. Take the plastic circle you have just cut out and the spring terminal with the wire on it and push it down the tube. you want the wire to pop out of the hole you made for the switch.
6. Solder the wire onto the switch. Also solder the other wire coming from the negative end of the LED to the other end of the switch
7. Finally Solder the Positive terminal (coming from the switch in the first half of the pen) to the other plate you removed from the battery compartment.
8. Push it all together! I added some heatshrink tubing over my design and also added an ON and OFF Label.
When I get the time on the weekend I'll take some more photos and add them.
