Adjustable Single Lever Morse Code Key (CW Paddle)

This is a Morse Code Single Lever Paddle (CW Key) designed for amateur radio operation. It features an adjustable spring mechanism using standard ballpoint pen springs, allowing you to fine-tune the tension and tactile feedback. Key Features: Simple Design: Consists of only two main 3D printable parts (Base and Arm). Support-Free Print: Optimized to print easily without any support material. Adjustable Tension: Uses 2x standard ballpoint pen springs. Tension is set by turning the M3 bolts. Hidden Wiring: Wires from the side contacts are routed through the body and run along V-shaped grooves at the bottom for a clean setup. Desktop Mounting: Includes three 4mm holes for bolting the key down to your desk or a heavy baseplate. Required Hardware (BOM): Bolts: 3mm (M3) bolts for contacts and adjustment. Springs: 2x standard ballpoint pen springs (cut to length). Nuts: M3 nuts for securing contacts. Connector: 3.5mm stereo jack. Check out my other Morse Key design: If you prefer a simpler, n
