Dr. Davis: It is pretty amazing how much it has taken off. And one thing which has been wonderful about it, too, is that all along, Karl has said that he is not charging for the mass clips at all. But there were so many optometrists that asked if they could make donations that I set up on my office webpage a place where they could make donations for him. And his project just received almost $2,000 in donations. At this point.
Bailey: I didn't realize you weren't charging for them. That was going to be my next question. So, that's vary altruistic. Are you charging shipping?
Dr. Davis: We don't.
Karl: That's part of the reason why we put up the donations button and so that people could donate for material cost and for shipping. So, we are sending these out with first class mail now.
Dr. Davis: Yep.
Bailey: That's great. So, $2,000 in donations and were you are you using that money to offset costs and shipping, or do you have other plans for that money?
Karl: I am using it for shipping and for material costs right now, but I might buy another printer with that.
Bailey: Oh, that's a good idea. That way you can manufacturer even more. How much do 3D printers cost? I have no idea.
Karl: It really depends on what size and how good you want it to be. If you want, a small desktop 3D printer that is all packaged and works right out of the box, you can get one for like $250. If you want one that is larger, but you have to assemble it yourself, then you can get that for like $275. But if you want a professional manufacturing, high-quality printer, it can cost anywhere from $5000 to $200,000. It just depends on quality and size and all that.
Dr. Davis: The printer that he uses for most everything has two different printers. One of them is an intro level one that he has been using for the child size ones, and the other one is his main printer. And your main printer is about $400?
Karl: About $300.
Dr. Davis: About $300 to $400, something like that. I don't know if this will work or not, but that is the printer in operation. [Shows the printer]
