Solar Powered Flashlight

thingiverse

This is a 3D printable solar powered flashlight designed to benefit low-income communities with access to 3D printers, solar panels and batteries. The main idea is to provide them with an easy-to-print design that can hold a circuit board, on/off button, LED, and input inside. The flashlight will be powered by a battery previously charged with solar energy, making it more affordable than buying new batteries or relying on the power grid. This design was created for the OSAT project in the 3D printing class at Principia College's engineering department under Dr. Marie Farson's guidance. The design includes a flashlight body and a lid carefully crafted to fit together perfectly, taking into account filament shrinkage. This product was designed using FreeCAD software, featuring two components: the flashlight and the lid. Both have independent STL, FreeCAD, and GCODE files available below.
