At a friend's suggestion of, "Why don't you make something really functional" and then proceeded to sketch out a design she had in mind for a stand for her iPhone. I took the sketch home and with the help of Autodesk Fusion 360 made her sketch come to life. Precisely engineered to work like you would want a tabletop stand for your smart phone to work, this is something that can really show off what your printer can do. The back leg assembly tilts from 0 - 45 degrees for all the adjustment you might want or need. The pivot joint has a 5 mm hole that will require you to buy a small bolt, 2 washers, nut or wing nut. The bolt and nut will create tension on the drum of the pivot joint and allow the back leg assembly to hold its position. Please feel free to contact me for any questions you might have about this model. Happy printing, Makers!
