Modular support for small frames

This modular support is specifically designed to lean small square frames (170 mm) against a bookshelf wall.

It measures 170x50 with a small 8mm rise, which allows the frame, even if unbalanced by some 3D print, to remain leaning against the wall without falling (since it is tilted).

To support multiple frames, one next to the other, and ensure they are all aligned, I designed modules that link to one another. This also helps prevent the frames from sliding because it creates a larger structure, improving friction with the horizontal shelf.
