Modular Frame system for paper, e.g. for ArUco markers or photos

thingiverse

This is a custom-designed modular frame-system created as part of my research thesis. It is engineered to detect ArUco markers from both sides, front and back, but can also be used for any other paper-like objects such as photos. 3D Print Instructions: - A single perimeter is sufficient. Infill at 15%. - You will need two printed half-frames to create one frame. - At least one holding clip is required for fixation, but I recommend using twelve of them, arranged as shown in the first image. Use a brim when printing multiple frames simultaneously. 2D Print Instructions: - The provided .svg can be used to adjust your markers, photos, or other content to fit the frame. The .svg is specifically designed for printing on a DIN A3 sheet. Build Instructions: - Place one half-frame on a flat surface and position your paper-like object within it, ensuring the cutout fits securely. - Rotate the second half-frame by 90° so that each side has two flanges, then secure the frame using holding clips. - If necessary, stretch the paper by moving the frame's sides and bending them inward over the paper. This may be required when using markers like ArUco for detection. Important: - When printing thick paper, it may be necessary to scale up the holding clips accordingly. I suggest testing a single clip print to ensure a proper fit.
