Hollow impossible heart

thingiverse

Initially, I created two unique heart models for a wedding gift - an entirely hollow and another with walls. The couple wanted assistance with their honeymoon, but my pride prevented a simple monetary gift. Thus, we opted for a fun challenge, where the money was concealed within the heart. Eventually, they had to figure out how to open it! I've also shared an OpenSCAD file to customize your own versions, including adjustable inside hole size and wall thickness settings. The file even contains codes for creating STLs of pieces with letters 'P' and 'B'. Printing these on a Prusa Mendel resulted in seamless fitting after smoothing the edges.
