Ploberger NiMH light convert to Lipol battery with charger

thingiverse

I was constantly fatigued by the tedious process of removing NiMH batteries for charging when light levels were weak. So, I took it upon myself to design an adapter that incorporated a Lipol battery from a cell phone and a charger for Li-ion batteries with built-in protection from China. The charging source is conveniently powered through USB. Due to manufacturing tolerances, the printed parts didn't perfectly match the original Ploberger components, necessitating some minor rasping to achieve a secure fit. Once assembled, all parts are securely glued together. LEDs embedded within the charger's PCB provide visual feedback. However, I'm currently in need of a short piece of transparent filament to enhance visibility, but unfortunately, I don't have any on hand at the moment.
