Solar Powered Flashlight

thingiverse

This is a 3D Printable Solar Powered Flashlight designed for low-income communities that have access to 3D Printers, Solar Panels and batteries. The main idea is to provide them with an easy to print design big enough to hold a circuit board, on/off button, led and input inside. The flashlight will be powered by a battery that was previously powered with solar energy, therefore it wouldn't be as expensive as buying batteries once they run out or as unsustainable as using the power grid to recharge them. This designed was a result of the OSAT project for the 3D printing class in the engineering department of Principia College directed by Dr. Marie Farson. The design includes a flashlight body and a lid, which have been carefully designed taking into account filament shrinking, so they can fit together. This product was designed in FreeCAD, and there are two components: The flashlight and the lid. Both have independent STL, FreeCAD and GCODE files that are provided below.
