This is a phone case with a llama cutout for pictures. A custom phone case costs around $20 to $40, depending on design and detail. This printable phone case costs roughly $1 and can be printed in multiple colors and filaments, although a flexible filament would be best.
Tha llama cut out was created by taking an image and tracing the bitmap in Inkscape. This was then converted to a scad file and extruded in OpenSCAD using the following extension https://www.thingiverse.com/thing:2805184/files. The llama STL saved from openSCAD and the phone case were edited in Blender by differencing the llama outline from the case. The case itself was found on Thingiverse: https://www.thingiverse.com/thing:2722392/files
