21700 Battery Holder and Case 3D Models

«21700 Battery Holder and Case 3D Models»

Some models are open holders that keep cells upright in a drawer or on a desk, while others are enclosed travel cases with lids to prevent contact with metal objects. You will also find pack frames meant for assembling cells into larger power banks, often shaped for specific series-and-parallel layouts. End caps and terminal covers appear as well, offering a simple way to insulate contacts without a full enclosure.

Check the author’s page for the exact dimensions and whether the model is sized for bare cells or wrapped ones, since 21700 sizes can vary slightly by manufacturer. Look at how many parts need printing and whether assembly requires hardware like screws or springs; some holders use integrated flexible arms, while others rely on separate metal contacts. Photos of real prints help you judge wall thickness and fit before you commit filament and time.

If you need a different format, try searching for 18650 or 26650 holders, because many designs cover multiple cylindrical cell sizes in one tray. For power-bank projects, add terms like “pack frame” or “cap holder,” and if you want something portable, include “travel case” or “box.”
