Seamless Background Supports for Poster Board

Want to elevate your photo's of your recent projects? This simple seamless background support is to be used with your normal poster board that you find at your local dollar store or walmarts of the world to create a clean and simple background. There are no supports required for these. I also designed simple brackets that fit perfect on 5mm thick foam core boards as well. https://www.printables.com/model/1206321-5mm-foam-core-corner-brackets-for-photo-backdrop
