What it does

Shaped with round cutouts sized for 18650 cells, so cells sit side by side
Open pads on top, so nickel strip has room for spot welding or soldering
Edges shaped to line up with another holder, so you can build larger packs
Printed in PLA, made to order in the USA after you order
Plain spacer shape, so you can plan your own pack layout

18650 Spacer Holder sits under your cells and gives each one its own round slot. It is shaped for 18650 lithium-ion cells, with open pads on top so nickel strip has room for spot welding or soldering.

The edges are shaped to line up with another holder, so you can plan a pack that is bigger than one holder alone. This makes it useful for anyone building a custom battery pack for tools, lights, or other projects that run on 18650 cells.

This is a plain spacer shape. It does not include any cells, nickel strip, or wiring. It is printed in PLA and made to order in the USA after you place your order.

12k downloads in the maker community. That is interest in the design on the site it came from, not our sales.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
