I’ve been spending a lot of time on CNC lately.  Quite a while ago I wrote about mounting my Olimex MT-128 circuit board in a plastic box to make it easy to take with me places.  That was a good idea, and it certainly kept the cat away from my projects.  Unfortunately, it also made it quite difficult for me to work on a project.  The problem was in getting to the back of the circuit board to plug in programming headers, connect to pins, etc.  For some reason it took a while for me to realize the neatest, cleanest solution: mount the experiment board to the top of the pencil box.  Genius!

 

Not so fast, though.  I tried that once before and it was mostly a failure.  Trying to hack up a flimsy plastic box with any precision is no easy task.  This time, though, I was armed with a lot of recent CNC experience.  I opened up TurboCAD and drew up the dimensions (or so...
