Poster Frame Corner Protectors

These corner protectors were made to safeguard the corners of a couple poster frames I was selling, so that when the buyers loaded them in their vehicles they could rest assured that the corners were undamaged and in the same condition that they saw in the listing photos. 

Simply print in PLA, then apply a small amount of heat - by heat gun, lighter, or match - and form them to your poster frame. The small amount of heat required to make PLA malleable will not damage anything on the poster. My posters had very thin flexible acrylic front panels, and I couldn't even see a hint of a mark after applying these. You could also opt to print these and leave these as-is, then simply tape them in place.
