Introduction: Make a Portable Arduino Case
I was really disappointed to see that the Arduino case carried by Adafruit was discontinued (due to that model of Otterbox being unavailable): http://www.adafruit.com/products/765
However, a quick Amazon search showed that an Otterbox 3000 could be had, and the pattern for the acrylic insert is available on Thingiverse: http://www.thingiverse.com/thing:20523
So, I set out to make my own! I made it at TechShop (Pittsburgh) http://www.techshop.ws/index.html

Step 1: Step 1: Create Acrylic Insert
I downloaded the pattern for the acrylic insert from Thingiverse: http://www.thingiverse.com/thing:20523
I made a few modifications to the pattern in CorelDraw - the pattern as downloaded was is CMYK, and the laser cutter/software settings I use are in RGB. I also removed the etched text, for simplicity.
I printed the pattern on paper first and checked it against the box, arduino, breadboard and tin, to make sure that everything fit. Check!
I then used the laser at TechShop Pittsburgh to cut the part from 1/8" acrylic - the default acrylic settings on the lazer worked just fine.
Step 2: Step 2: Test Fit
I discovered that the Otterbox I had ordered from Amazon had one major difference to the one originally used by Adafruit - it came with a foam liner that needed to be removed. A little time and some Goo Gone for the adhesive took care of that.
I checked the fit of the insert in the box, and of the breadboard and mint tin; the breadboard's tabs did not fit exactly, but close enough with a little wiggling.
Step 3: Step 3: Attach Parts and Assemble
I used parts from two sets of RadioShack computer standoffs (10 mm and 20mm) to attach the Arduino. I used the shorter standoffs - just enough to lift the USB connector above the level of the case edge, so that it is easy to plug in. I needed to use the longer screws from the other set, however, to reach through the 1/4" acrylic.
I also used foam tape on the back of the breadboard and velcro tape on the back of the mint tin, so that those items would help hold the insert and Arduino in place in the box.
Once everything was assembled, I gave it a good shake - nothing moved, This is a durable, waterproof travel case for your Arduino and accessories.
