NOTE: If you're interested in reading about a printing discovery I made during this project, read my other post called "Speed Up 3D Printing" - which could have been titled: "How I made my 3D Printing 62% Faster".
The NeedI haven't seen a good mini-organizer for storing these, so I figured I'd "invent" one (yeah - I use that term very loosely - as it's not exactly an invention, more like a custom thingy). The Button Battery Box (tm, patent pending, not) will store bunches of button batteries safely and efficiently. I'm of course starting with a size that works well for the batteries I have laying around - the LR44 - and then I'll move on to the CR2032.
The 3D Model Solution
The method I used was to create the outer container box first, then to use slats to break up the main compartment into equally sized tiny compartments for one battery each. This was tedious to get the measurements right. The only benefit to this method was that it made it easy to have the outer walls of the box have a different (higher) height than the inner walls.
The method I SHOULD have used (which I have used in other applications) is to create one single battery tiny compartment and then replicate it and put them all together to form a larger box of individual spaces. While that would have required me to build up the side walls separately, it would have been easier than setting up the slats in perfect separation from each other (although 123D does have a simple method for that too).
Next step will be to create a similar box for other parts - then to make a holder for all these boxes that looks like a miniature dresser :)
