This thesis outlines the process of creating an ergonomically shaped didactic aid designed to teach the correct violin bow hold and positioning of all the fingers of the right hand. In doing so, reverse engineering was utilized in conjunction with 3D printing. The thesis begins with an overview of the learning process of violin playing and lists existing insights into potential problems beginners face when playing with a bow. Taking into account the state of the art in didactic aids for violinists and their role in promoting the correct bow hold, the conceptualization of an optimized version of the aid was initiated. Due to its ease of reshaping, plasticine was chosen as the material for the prototype. To protect the bow from hard-to-remove plasticine residue, reverse engineering was first applied to the bow frog. The process of structured-light 3D scanning is used in the creating a replica of the 3D CAD model of the bow frog. Other parts of the bow, due to their large dimensions and simple shapes, were designed using CAD software. The assembled bow parts were successfully 3D printed and used for shaping the plasticine prototype. The primary guideline in conceptualizing the aid was to maintain the necessary joint agility while also restricting finger movement to their correct positions. The aid was designed in the shape of an elephant's head to make it as child-friendly as possible, given that children are the main users. The same reverse engineering process used for the bow frog was applied to the aid prototype, with additional software used for refining and reshaping details and surface texture. The final model was then fabricated using 3D printer with adjusted settings for the flexible filament. The chosen material is suitable because it ensures ergonomics during use and ease of installation on the bow with a wide range of choice in regards to the filament color, which can therefore be personalized. Ultimately, this is so far one of the very rare didactic aids developed for the purpose of learning the correct bow hold for violinists made in a single undivided piece and can be fastened on the bow without its disassemble into parts, while simultaneously ensuring the correction and guidance of all five fingers of the right hand.
