I only spent two and a half hours on the first link, and about an hour on the second one. Definitely a LOT of great projects, bur there is one major issue I've found with every one of them...
I now NEED to buy a 3D printer. I thought that at my age, I could quietly pass on by 3D, but I think I've been snagged.
Thank you, it is very good info and plans.
