No doubt, but don't ya just love putting fans and ..... in things?...I'd also drill a couple 5mm holes through the bottom and install a couple orange or red leds for some ground effects lighting...nothing gets chicks like ground effects lighting...or so my kid says
Perhaps you should throw some ground effects on your mailbox Quig. Just recalling what you were saying about your post woman.
Got a new mail "man"!
...turns out hot mail chick is off on maternity, pfft!...trashed my whole day when I heard that 
I believe just swapping the 10k ohm pot with a 5k ohm will give a better adjustment for the 'vaping range', according to previous discussions about this.
Picked this up today - Unique Wooden Box handmade Brown Decorative With Latch | eBay
Gonna make a desk top PT using either the larger LM2596 - LM2596 DC-DC Converter 4-40V to 1.5-35V Step-down Adjustable Power Supply Module | eBay
or this kis 3r33 plug-n-play module. I have both modules around here somewhere, just can't find either at the moment. I ordered another kis-3r33 module today also. Also have a slightly smaller box on the way that I may put together with one of the smaller LM2596s.
Ooops, fergot togive the devil his duecredit for the idea - http://www.e-cigarette-forum.com/forum/modding-forum/192284-dear-gummy-17.html#post6508163
Finally found my large LM2596 and kis-3r33s yesterday. Had bought a small plastic bin to put some stuff in and had put it in the back of a closet, where it'd be out of the way and all in one place
Anyhow now to wait for the rest of the pieces to get here.

Finally finished my dual 18650 bottom feeder, it may not be the cleanest work ever, but it works darn well, and it's solid. It gave me fits, and it was super hard to fit everything inside, but in the end it was worth it. Thanks to everyone who posted before me who gave me ideas and the know how to implement them safely and correctly. Loving vv regulation coupled with awesome battery life and juice delivery!

So is it really so simple????? +- input side and +- output side? Master switch on input and atty switch on output? Does it matter if the atty switch is on the +- or - side? Working on my first 2596 and the wiring just seems too easy.
It really is that easy, Don. That's all it takes unless you want to add a meter or other frills. Atty switch can be whereever you want it; pos, neg, input, output.... Won't make a noticeable difference.

So just wired up my 2596 board and getting an output voltage range of just. .5-2.7v. Green version of the board. Any idea why so low?
Input voltage is 8.4 using two sony 18650s.

It will take SEVERAL turns of the screw to get the voltage up to read correctly. Trust me. I found out the hard way, lol. Once you get it up to show about 3 volts, it should change by .5 volts per 1/4 turn. But like I said it will take SEVERAL turns to get there.
Took about 10 turns to get the range i am getting. After 2.7v an additional two turns did nothing.
Did some checking with my meter this morning. Each full turn of the adjustment screw is only changing my vout by 0.09v. Cant figure this out.
Edit. Checked the full adjustment range and appear to be off by a factor of 10. Ie. Getting 0.05v of actual adjustment for every 0.5v i should be getting. The question is why.

UPDATE: figured it out and want to share in case someone else has the same problem.
Pin 4 on the 2596 was poorly soldiered and slightly loose. A dab of flux and a touch of the soldering iron and it is now working properly.
Frustrating to have to troubleshoot and fix a brand new part but how much QC can we really expect from a $2 circuit board that has $4 worth of components on it. Lol.

I know it took me 2 days to play with it to get it right, but once I got it to where it was reading right the adjustments are SMALL. Glad you get it working.
Well FINALLY found me a box to do a 2x 18650 VV Box mod to play with, lol. It looks just like a minature lunch box with handle, lol. But it's pocket size and is Perfect size for what I was looking for. Here's a pic.
I got lazy about wiring and such and bought circuit board on EBay. We will see how it goes.
Plan on using 4 each 2000 mAh "AA" NIMH batteries, ala PUCK.
Probably start at 3.6 volts through a 2.0 ohm atty for a 1.8 amp / 6.5 watt Vape
Not sure what the overhead voltage drop will be but that will be the deciding factor in settings and ohm selection.
I will be using a rebuildable stardust that takes the Vivi Max atty heads.
Will post pics upon completion.

You need 2 to 2.5 V more voltage going in than coming out so you are really restricted with those batteries and the discharge rate on the batteries is probably too low.
Your max voltage under load will be below 3 v with those batteries.

So I'm looking at these on eBay. My question that I'm sure has been answered though I haven't been able to find is about the amp rating. The green one seems to be good only to 2 amps, while the red says 3 amps. How important is this?
