Penrose triangle pendant (1)

Pendant showcasing a mesmerizing Penrose triangle design, an impossible figure that appears as intended only from one specific vantage point. However, when viewed from other angles, the curved edges of this cleverly crafted pendant reveal its ingenious trickery. On the reverse side of this unique pendant, two adjustable diameter holes are strategically positioned to facilitate rope attachment. To create a seamless rope connection, start by carefully heating a thin synthetic rope until it reaches its molten state. Then, swiftly pull on the heated end to stretch and thin it out. Next, insert the molten end into one of the holes, using pliers to guide it through while simultaneously tying a knot. Once complete, carefully cut the excess rope and pull the knot back into place. This thoughtfully designed pendant was created using OpenSCAD software, with optional support structures available for added convenience.
