Customizable End Caps – Text & Symbols

These fully parametric end caps are designed to cleanly finish rods or tubes in modular builds — while also adding clear visual labels and engraved symbols.Designed in OpenSCAD, this model lets you easily customize:rod / tube diameterwall thickness and tolerancesengraved text (e.g. M6, M8, size labels)decorative or functional front symbolsPerfect for modular frames, workshop builds, display systems, educational setups, or storage solutions, where clarity and a clean finish matter. This model is part of my Modular Connectors system, designed for building flexible, scalable structures from simple elements.
