SummaryA simple guitar nut for a 3 string cigar box guitar. You can also use it as a simple bridge. It is designed for a 1 inch neck width. Top side of the nut is square Bottom side is a half round to increase gluing surface area. I used ABS with 100% fill for maximum strength. Notches may require a small amount of filing depending on your strings' gaugePrint SettingsPrinter Brand: PrintrbotPrinter: Simple BlackRafts: NoSupports: NoInfill: 100%
