LiFePO4 Battery 3D Models and STL Files

This collection gathers 3D models tied to lithium iron phosphate batteries: holders and trays for packs, enclosures for charger boards, adapters that let cylindrical cells sit in everyday devices, and cases for portable power builds. It is useful when a ready-made part does not match the cell size or the space you have. Each listing is an STL or similar file you can slice for your own 3D printer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

Come è composta questa raccolta

Polyzon compone questa raccolta a partire dai risultati di ricerca dei siti collegati. I doppioni e i modelli senza anteprima vengono rimossi, le corrispondenze deboli finiscono in fondo e il resto mantiene l’ordine dei risultati. I modelli appartengono ai rispettivi autori: verifica le condizioni sulla pagina di ciascun modello.

«LiFePO4 Battery 3D Models and STL Files»

Enclosures and trays make up a large share: some are simple boxes for a single pack, others are multi-part shells with room for a protection board, terminals and wiring. Adapters form a second group, holding a cylindrical cell inside a device designed for a different battery format, so the internal diameter and contact position matter most. Charger and module housings are a third group, sized around a board footprint rather than around the cell itself.

On the author's model page, look at the stated cell format and count, the outer dimensions, and how many separate parts the build has. Check whether supports are needed, which material and settings the author lists, and whether photos of real prints are shown. For a pack enclosure, confirm how the cells are retained and where the wiring exits before you commit filament.

If the results feel narrow, try synonyms and related terms: LFP, LiFePO4, 18650, 32140, 33140, 12V pack, battery box, cell holder, spacer, cap. Searches such as power bank case, emergency start box or charger module enclosure often surface the same kind of part. Adding a cell count or a voltage to the query narrows it further.

FAQ

Domande frequenti

Which cell formats appear in these models?
Most listings are built around cylindrical cells such as 18650, 14500 and the larger 32140 or 33140 sizes, plus multi-cell packs wired in series or parallel. The format is usually named in the title or the description.
Do these models need supports?
It depends on the geometry: flat boxes and trays often print without them, while overhangs around terminals, clips or screw bosses may need them. The author's page usually says so, and the photos show how the part was oriented.
How do I check that a holder matches my cells?
Compare the internal dimensions given by the author with the diameter and length of your cells, and allow for contacts, springs or a protection board. If the model is parametric, you can adjust the cavity instead of scaling the whole part.
Can a model be scaled to a different battery size?
Scaling changes wall thickness and the fit of screws, terminals and lids at the same time, so it rarely works for a large change. It is usually better to find a model made for that format or to edit the cavity in CAD.
