The simplest designs are often the hardest to make — this pendant is a perfect example.

When it comes to 3D printing, geometry does a lot more than define how something looks. Curves and contours aren't just aesthetic choices but structural components. They distribute stress across a surface and give a print something to build on layer by layer.

That's exactly the challenge here. By simplifying the sides of this pendant into a straight pill shape, we removed the very curves that were keeping it structurally sound — leading to warping, weak points, and failed prints.

To solve it, we went back into the geometry and made a few targeted adjustments: widening the layer lines through the extrusion and speed — these are some factors among dozens in 3D printing that could be causing these issues.

It turns out Jenga blocks are actually a great analogy for how 3D printing works. Stacking the blocks at an angle on the short side is similar to thin layer lines, with less surface area to stick to, creating a steep overhang. Stacking the blocks on the long side represents wider layer lines, giving each layer more material to adhere to and resulting in shallower overhangs.
