Made a more discreete photo holder that won't let it droop. Given its design you can print as many as you need to fully support your photo. It comes in 2 sizes, 107.5 mm (Photo_HolderV2_10deg) and 154 mm (Vert_Photo_HolderV2_10deg) tall with a 1 mm gap for the photo. Both are angeled at 10 degrees although can be very easily altered to any angle.
The author marked this model as their own original creation.
