This post is to serve as a reminder in case you forgot or missed my first announcement.You may have seen my 3D Printed Curta Calculator here on /r/3Dprinting or on Adam Savage’s unboxing at tested.com. I’ve built two of them (the first for myself).I have been asked to do an AMA. Don’t miss it tomorrow at 3pm EST! http://ift.tt/2jFtYwq
