Mandolin String Winder

This is a simple string winder for a mandolin with tuning pegs that are approximately 16 mm long x 8.5 mm wide. The two pieces can be printed together at the same time and affixed using an M3 bolt (I used an M3x20 Hex Socket Head Bolt). I placed a metal M3 washer between the two parts to help reduce friction. The hole in the handle should be a friction fit, and the M3 bolt can thread directly into the plastic.
