Battery Case STL Models for 18650 and 21700 Cells

This collection gathers 3D models for battery cases and holders, from single-cell sleeves to multi-cell packs. Most files are made for 3D printing, and many can be adjusted to the cells you already have. It is a starting point if you need to store, carry or mount cells in a project. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Battery Case STL Models for 18650 and 21700 Cells»

The reference shows several distinct groups. Cylindrical li-ion cases cover single and dual cells, while holders for AA, AAA, 9V and coin cells tend to be flatter trays or stackable racks. Print-in-place and hinged designs close without separate hardware, and power-tool holders follow the outline of a particular battery pack. Multi-cell packs add wiring channels and spacers between cells.

Before printing, compare the cell designation with the dimensions on the author's model page: 18650 and 21700 differ in both diameter and length, and coin cells are much thinner. Look at the number of parts, whether the design needs supports, and how contacts or springs are handled. The material and settings the author lists, together with photos of real prints, tell you more than a render.

Search terms can be widened when a query returns few results. Try holder, caddy, tray, sleeve, enclosure, spacer or pack instead of case, and add the cell type — 18650, 21700, AA, AAA, CR2032, 9V. Related topics include power-tool battery adapters, cell spacers for spot welding, and racks for loose cells.

FAQ

よくある質問

What is the difference between a battery case and a battery holder?
A case usually encloses the cells, while a holder keeps them in position and often includes contacts or springs. Some models combine both functions in one part.
How do I pick the right size for my cells?
Check the cell designation and measure the cells you have. 18650 and 21700 differ in diameter and length, so compare your measurements with the dimensions the author lists.
Do these models need supports?
It depends on overhangs and internal cavities. The author's page often states whether supports are needed and how the part should be oriented on the bed.
Can a battery case be scaled to another cell size?
Scaling changes wall thickness and the spacing between contacts, so it works better for small adjustments. Parametric models let you set the dimensions directly instead.
