Solstie's ukelele headstock that accepts metal guitar tuning machines. I remixed it to fit onto the Makerlele_Mk1_Plus. This upgrade ruins the cool, entirely 3d printed aspect of the Makerlele, but it adds a great deal of playability. Metal tuning machines hold tune better than their 3d printed derivatives. Visit FreshPrints3D.com for more cool 3D printed stuff!I printed mine with no top or bottom layers and ~30% honeycomb infill. Raise the layer height to complete the print faster. Use at least 4 walls/perimeters.
