The arduino hardcase is a lasercut acrylic case that protects your arduino's ports and headers from being knocked off in a bag or backpack. It also provides a standard bolt pattern for mounting the arduino on another project. Holes cut in top piece allow easy access to the headers and the reset button, and with slight modifications shields could be added/enclosed.
I made it in about 3 hours in an effort to procrastinate on another project.
it should take about 6-7 minutes to cut on a laser, and 10-15 minutes to assemble. It is made from 1/8th inch acrylic, 1/4 inch acrylic, and some nuts'n bolts ( I used english but feel free to modify the hole size for metric). I'll post Dxf files and full assembly instructions later tonight.
