The printable files are the body, head and neck of the Ukulele together with an additional flame extensions that extends the body. You will have to buy some additional parts: the strings, tuning pegs and glue. On the Cubify website, for the CubePro 3D printer, they specify that it will take about 2 days at 200 microns or ~4 days at 70 microns and use approximately 2 CubePro 3D printer cartridges. You should give it overnight for the glue to dry as well.
This is a great musical project and a good looking ukulele so why not give it a go. IF you build one we would be grateful for any photos to put up. If you create an account before you download you can leave a review of the model files and tell us about your builder experience and what you built it on.
