I'm sure I saw those stalk benders in one of his posts bro. I'm going to need to find it and recreate it for print, because I remember thinking "I need some of those." when I saw them.
They would be easy and fast too, could probably print 5-10 per hour or more :D
And yes something like that, could stuff 20 of them in an envelope and it would still weigh barely anything and be relatively slim. I'm sure we can make it happen.
Yeah! Maybe you could start a casual side business out of it, even. Probably a market for it, especially if you can do it for a reasonable cost (power, filament, etc).
