Impressive! Suggestion: It would be nice to include a price list on the article. This project is impressive as heck, but aside from being intellectually out-of-reach for most kids, it would be financially challenging as well. Last I looked, CNC aluminum blocks were well out of the reach of 99.9% of kids (but that was decades ago; perhaps prices went down). For people wanting to follow in those footsteps, it'd be nice…
So there's probably a price there, but it's probably well under $1k
Price list would be cool to have
