Clock Kit Case

Case for the cheap [clock kits available on eBay](http://www.ebay.com/sch/i.html?_odkw=c5+4+bits+digital+electronic+clock+diy+kit&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.A0.H0.Xc51+4+bits+digital+electronic+clock+diy+kit.TRS1&_nkw=c51+4+bits+digital+electronic+clock+diy+kit&_sacat=0) for about $2.50. The clock kit is a good solder practice item, and this case should cover up the electronics nicely.

I'm not working on this any more, but it does still need a bit of work. I ran the clock on 3xAA, and it lasted 2 days, tops. From that, I think running it off batteries is a bad idea. I'd like the case to have a mount for a power supply jack, but don't have time to continue revising the design.

v4 (current):

* redesigned entire part in openSCAD, with user variables
* added optional AA battery compartment
* added option of mounting PCB with a screw or a plastic rivet
* combined buttons into one part that glues to the top part of the case
* added a lip to more easily attach the two parts to each other
* added license + contact to SCAD files

v3:

* fixed the display lip
* fixed the connection parts
* shifted the button holes closer to directly over the buttons
* evened out the thicknesses of both pieces' bases
* added buttons to go in the button holes
