This is for a 3000mAh 3.7v lipo style battery.
Printed on a Bambu P1S with no supports, but with an outer brim.
I'd recommend supports for the overhangs.
Generic PLA with 0.20mm Standard quality.
The author remixed this model.
I enlarged the overall piece to fit the 3K mAh battery. Then I modified the side bracing to better fit the hold-down strap I'm using, as shown in the photos.
