Thanks so much asdaq, I did all the milling on a bridgeport series 2 running on Mach3 CNC software, and designed from sketchup to CAD to CAMBAM, it was a huge learning experience to do CNC machining as all I have done in the past in manual machining. The overall size is about 1-3/8" deep X 3" width X 4" height. it does seem intimidating when you first hold it but after a short while feels much more comfortable. and the weight is much less than I thought it would be also. I was scared of that fact when I began the project hahah
