Case for the cheap clock kits available on eBay 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
