3D printer battery pack casing

This design is for a solar powered 3D printer (MOST delta) battery casing (14.8V, 20Ah Li-ion). It has two side holes for switches and a small top hole for the LED indicator. More screw holes can be added to the print or just drilled after the design is printed. Printing upside down takes approximately 5 hours. The design can be customized as desired.
