A tankomizer has the following advantages :
* Longer lasting (the 20ml syringes model holds ~4ml e-liquid)
* A more consistent vape and much less chance of filler burning
* Can see when to refill (no guessing)
* Cartomizers will have a longer life (can be used for longer)
Tankomizer build instructions ...
Requires (minimum): 2 x syringes (w/o needles). 10ml : slim; 20ml standard; 30ml : fat.
Cost only ~ $0.20 - $0.60 each. For example, Animal Health Express
Time to make : ~ 20 minutes.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1) Punch hole or hacksaw / dremel (2mm open) slot in cartomizer, 1.5 - 2 cm above the connector (so that it will be above the rubber stopper and open to the liquid in the tank).
Punch method
Either use a sharp tough screw and hammer (and care) or, best, a 'saddle valve' (do a couple of turns after it 'pops' through).
Dremel / Hacksaw method (preferred, seems to be more reliable at achieving a good result)
Make a 'slot' (~1mm wide). If use a dremel, make sure carto filler is damp first (prevents melting).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2) Cut a section of plastic syringe tube to a bit shorter than carto (with a pipe-cutter, hacksaw or sharp knife).
File edges smooth, especially the insides. A pipe cutter works well for this; then little or no filing is necessary.
When using a tube cutter it's necessary to put a dowel or metal tube inside the syringe barrel so that it doesn't get squashed while cutting.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3) Use an old carto to punch holes in the rubber stoppers (a rubber mallet is ideal).
Place on a hard flat surface (with a sheet of paper between) and tap the connector end to punch through the plungers.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4) The tankomiser can now be used, but to make refilling easy, a plugged refill hole can be made in the outer syringe tube (near one end).
Earing-back method
A belt hole punch works well for a small hole through the syringe barrel. A rubber earring back fits perfectly in the 2nd smallest hole that the belt hole punch will make.
One problem with the earring backs is that they have a small hole in them that the earring post goes through. This has to be stopped up in order to use them as a stopper. There are a variety of things you can use to stop up the hole. You can use a head pin (jewelery finding used to make earrings), you can use an actual post earring (have to clip off some of the post), you could use a thumb tack, a stick pin, anything small enough to fit through the hole.
If you're a girl, add a crystal or some sort of decorative thing.
Or, earing cushions like these would work well (fit a 1/8" hole (but check the brand you have/buy for best size) and are about 1/4" at their widest) :

Small plunger method (larger hole)
Uses the rubber plunger from a small plastic syringe; 3ml size or smaller.
Drill a hole a little smaller than the plunger's between-rings diameter (drill a pilot hole first of all) and then use the plunger to seal the hole.
Alternatively, use a dremmel. First use the weird little screw-like bit, then a routing bit to open the hole up to the right size.
Some people use a leather wheel punch.
Another possibility :
10ml and 3ml Excel syringe plunger holders. "The 10ml one fit tight in the 1/8th hole I had punched for the earring rubber. Obviously the 3ml would need a smaller hole. I have no idea what size though. Now these stick out further than the earring rubbers do. For that reason I prefer the rubbers. But hey, if you don't want to have to buy yet another thing, and you have a workable plunger laying around, why not give it a try. Note that the 20ml excel plungers (at least the ones I have) have a different tip on them that is not suitable."

5) Assemble like this :
Build up a collection for different flavors :
A 10ml syringe (BD brand at least) can (just) fit into the common 2xAA hobby box, making a long-lasting yet small unit :
