The electrical charger for an electric bike is equipped with high-voltage and high-current specifications, namely 34V DC - 3.4A. Notably, the cable lacks a sensor switch or safety pin that would only activate the 34V circuit when a bike is properly connected. However, this can be easily addressed using a MOSFET, thereby preventing pin burnout and potential electrical hazards. Moreover, to avoid any short circuits, it's recommended to include a safety cap, particularly when working with an unfamiliar charger or cable configuration. Here are the print settings used for this project: Printer Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Resolution: 0.1 mm (or 0.2 mm, it doesn't matter) Infill: 60% Post-Printing Instructions To assemble the charger, follow these steps: Borrow a hair rubber band from someone you know and use a string to thread it through the holes. Once complete, tie a knot to secure the rubber band in place. The rubber band will make it easy to use the charger. Design Process During the design process, I utilized a caliper (I learned a new word).
