Hearts

thingiverse

Easy-to-print Valentine's Day hearts, inspired by the number 6 plane curve on MathWorld, are available in five designs. These include a heart with a safety pin fitting (pin.stl), a small box (box.stl), a lid for the box (lid.stl), and two single-sided pendant variants (pendant_mark_01.stl and pendant_mark_02.stl). OpenSCAD code is also provided. Printing instructions are as follows: the lid and pendant_mark_02.stl require support, while the pin can be printed directly on the build surface or with support for a more polished backside. Pendant_mark_01 and the box can print directly on the platform without support. Lastly, secure a safety pin to the pin's back using a small piece of 1.8mm printing plastic, or glue two single-sided pendants together for a double-sided pendant with a finished look.
