Box for Almost Impossible Heart puzzle

thingiverse

This box is designed for an "Almost Impossible Heart" shape but can be modified to suit other STL files. The heart shape is imported and then enlarged before being cut out from the top and bottom halves of the box. OpenSCAD's parametric capabilities enable customization of various features such as height, width, depth, bevel size on top, mating lip size, and the STL file imported into the design. Additionally, users can adjust the degree to which the STL cutout is oversized. To edit the box's parameters, alter the .scad file where all adjustable variables are listed. The "part_layout" option allows for printing with both pieces open, closed or slightly separated for fit checks. Replace "heart.stl" in the file with your desired STL part, remove the "scale" directive above it if necessary, then compile and render using OpenSCAD before exporting as an STL file. It also makes a fun Play-Doh mold!
