3S 18650 sled for 1590B

thingiverse

This is a remix of discojon's 3 x 18650 battery sled for Hammond 1590B, remixed for optimization with a 1590B enclosure providing ample room up top. The original sled is very well designed and extremely durable; I simply added polarity markers and notched the bottom corners to enhance functionality. A small notch was also created at the top to accommodate another component mounted on the back side of the enclosure. Five large clips are used for battery springs, with all three top contacts utilizing these large clips - Keystone Electronics part number 209 (https://www.digikey.com/product-detail/en/keystone-electronics/209/36-209-ND/151583). On the bottom, a single large clip is placed in the center, while two small clips are positioned on the outer edges to prevent any potential shorts - Keystone Electronics part number 204 (https://www.digikey.com/product-detail/en/keystone-electronics/204/36-204-ND/227461). Custom Section A total of five large leaf springs/clips and two smaller ones are utilized for securing the batteries. However, users should exercise caution when employing large clips on the bottom edges to avoid grounding the batteries against the enclosure due to the tight fit.
