Frame and Picture of Nothing is Impossible
This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/fp6M0wBqzSH
I used 3 to 4 one inch strips of filament for the hinge
on the frame.
A little rubber on bottom of brace may help with sliding.
For lattice picture, I changed color of filament at 75%.
Makes a nice gift when sending a card.
