A compact 3D-printable battery sled designed to securely hold two 21700 cells. It features a snug fit, integrated contact slots, and a simple durable design ideal for custom electronics and battery-pack projects.
This sled uses Spring Battery Contacts, specifically ECSiNG Spring Battery Contacts for Keystone Electronics 209 from Amazon. Other contacts may be other sizes and may not fit.
Print completely solid. Never use off-brand 21700 cells. Polarity is at the discretion of the user. There are no markings to indicate polarity. Do not short circuit batteries. Do not use cells other than 21700s.
