gear wheel 3d model

A small mechanical rotating wheel designed for a string instrument attachment. The wheel is circular with a central hole for mounting on a motor shaft. Around the outer edge are evenly spaced, sharp triangular teeth shaped like guitar picks. Each tooth is slightly longer and angled backward to create a pronounced pick attack when rotating. The teeth tips are slightly rounded and flexible to reduce harsh scratching while maintaining an aggressive tone. The spacing between teeth is tight to allow near-continuous contact with a string. The material appears to be a matte soft polymer such as TPU or rubber, allowing slight flexibility and durability. The wheel has a diameter of about 20–30 mm and a thickness of 5–8 mm. The design is precise, symmetrical, and optimized for high-speed rotation, balancing strong attack with smooth contact on the string.
