Poster Frame Corner Brackets

thingiverse

Those flimsy, thin poster frames with pressure-fit edges that always come loose? They're terrible, constantly falling apart, but they're incredibly affordable and the next best option is several times pricier. Well, these small corner brackets resolve my issue with the edges falling off my poster frames. They need to be secured to the wall, but if it's a semi-permanent hanging location, it shouldn't be too harsh on your walls. Flip them upside down if you don't want to use supports, and use plenty of infill on these since they need to withstand a significant amount of flex stress.
