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 more room up top. This is a very well designed sled and plenty durable. I just added the polarity markers and notched the bottom corners. There's also a small notch up top, which was put there to make room for another component mounted on the back side of the enclosure. I use 5 large clips and 2 small clips for battery springs. All three top contacts use the large clips- https://www.digikey.com/product-detail/en/keystone-electronics/209/36-209-ND/151583 On the bottom I use a large clip in the middle, and 2 small clips on the outer edges to avoid any shorts- https://www.digikey.com/product-detail/en/keystone-electronics/204/36-204-ND/227461 Custom Section I use 5 large leaf springs/clips, and 2 of the smaller ones on the bottom ends. If you use large clips on the bottom edges be careful of grounding the batteries on the enclosure, it's a tight fit.
