Yep I had everything on the pic cut.
It says on there that that the bulk of the parts are 5mm (the main area on left of pic) and the others- the small area to the right- are 3mm.
I'm fetching it all tomorrow: the cutter guy is near my work.
I have yet to find the hex brass standoffs in all the sizes: my electronics supplier only has very short ones- I suppose for mounting boards in enclosures- and I'm not sure where to try next. But all in good time....
EDIT... re servos.... looks to me like the servos are readily accessible for replacement, at least going by the vids. So for the first build we'll probably just use the crappy 3x hobby servos we have (4.3kg), then upgrade later. Unless it looks like a pita to replace them, in which case I might spring for 3 decent ones up front.
Our objective here is to give my daughter a decent test- and development-bed for her studies. With a decent arm, and the flexibility this one gives for end-effectors, she can concentrate on the control side without having to worry about a crappy arm made of ice-cream sticks and rubber bands falling apart.
