Art framing can be ridiculously expensive. However, a good framing job makes the artwork look much, much better. With that in mind, I want to try printing a frame for a (art) print I bought. This is basic example of an art frame that can be printed on a 3d printer. Many different profiles can be made to suit many different types of art, but I just mocked up a quick one as an example of the basic principle. I've only supplied the Sketchup files for now, since you might want a different profile, or want to adjust the side lengths to fit your artwork or printer build area. I really just wanted to post this to get some feedback and refine the idea, but you should be able to print this and get a small frame as long as you have a .stl export plugin.Print out 4 (or more) side pieces [dark blue], and 4 of each type of corner piece (left hand and right hand). You'll also need 4 of the corner joining pieces [cyan].Once printed, just assemble it all together as shown in the picture to the left. The pieces have to be glued or screwed together, however I think the best solution will be just melting pieces together with a hot knife or soldering iron.Since this is just a proof of concept (for now) there is no allowance made for hanging hardware or joining multiple side pieces together or holding the artwork in place. Another concern is the surface will be a 3d printed surface, so not smooth. I think that "real" wood frames are covered with a putty or clay to even out the wood grain, and to give a smooth surface for gold leaf to adhere to. I think the same technique could be used here, possibly with better results, since the plastic won't expand and contract with humidity changes. the putty would also cover any gaps where the separate pieces are joined together.
