Ninebot Castlenut Wrench

This is a test. It was built from dimensions that were found online. I have not tested it yet. I suggest printing with a high number of walls, and an aggressive infill. I plan to create another version that will be adaptable to a socket wrench. Please comment your suggestions and findings.
