Mandolin strings winder

thingiverse

The original Thing print required extra hardware (bolt and nut), but now there's a new version that fits mandolins and possibly guitars with no additional tools. It's available in 3 versions - tight tolerance (0.5mm and 0.25), and two with more clearance (1mm, known as MachineHeadWinder_Blocky_MoreClearance.STL). The latest version, MachineHeadWinder_V3.STL, has a larger socket. Although raftless printing hasn't been tested, it should work. For UP! users, the original tight model is recommended; print at 0.25mm with default support and loose fill (1 down from solid).
