My glasses broke so rather than be a nerd and tape them up I decided to be an UltraNerd by 3D printing a set of frames! These glasses are the horn-rimmed style matching the FatHead brand prescription glasses (apparently I have a big head, how appropriate lol). See the instructions for how I did this with OpenSCAD. Update: made version 2 with the swept back earpieces that friction fit to my head just fine. I printed these in Aqua Translucent with zero percent infill and they printed fine on this Ultimaker (my old Printrbot would not have done so well on the inner flat of the bridge (nose) area. Anyway, with the new aqua glasses I feel like Aqua Man! lol...Les I took a photo of one lens frame of my broken glasses. Then I used an image processing program (Preview on the Mac) to resize the image down to 128 pixels wide and save as .png format. Then I read it into OpenSCAD with the suface function and used the constructive solid geometry features of OpenSCAD to section off the outline of the frame, clean it up, and mirror it. Then I stretched the frame tall and used two cylinders to cut it so that the goggle style tapers were formed. I'm working on a more exaggerated pair of glasses next. Les
