[edit]May I make a suggestion or two?[/edit]
Those suggestions are very welcome. Thanks.
Re: the leg attachment method. it's actually really strong. My prototype used epoxy glue but that was brittle. You could use tiny nuts and bolts instead if you like but I've found the wires to be quite effective. the thing has walked off the table and crashed to the floor many times. worst it suffered was crumpled antenna. You just have to be sure there's no shake in the joint when you first attach it.
