Capstan/string post washer - Hilo Baritone Ukulele

This washer was designed for a Hilo baritone ukulele. These were used at the local school which had several that had (~40) broken washers. This design could be adapted to other size guitars if the capstan (the rod the string wraps around in a guitar or ukulele) is a different size by simple scaling in the slicer.

Current inner diameter in the washer (hole that the capstan fits in) is 6.2 mm. Washer is nominal y 2 mm thick. 

If a different size hole is needed, scaling the part in the slicer should work.
