This frame is designed to be compatible with many household print sizes. Its simple design allows you to focus more on the art rather than the frame itself. It can also be adhered to the wall and the photo by using Blue Tack. It is perfect for small Polaroid like prints and only takes about 15 minutes to print a set of four and will print under almost any settings. Once mounted to the wall it is also very fast and easy to swap out photos. I have sucessfully hung photographic prints and posters up to 12x24 with this frame and have had no problem. Please feel free to post your creations using this frame in the comments below! I have also included the files for a double frame which makes it easy to maintain uniform spacing between pictures when forming a collage. Make sure to check back often! New versions and additions to this framing system are coming soon! I printed the frame shown in the picture with two perimeter walls and 60 percent infill and .25 layer height. Only a small amount of Blue Tack is needed for adhesion (see photos).
