Microsoft Designer Mouse Replacement Battery Cover

A friend lost the battery cover to their Microsoft Designer mouse. In trying to find a replacement, the closest they found was the Surface Mouse battery cover by crackFinder. It was similar, but the dimensions are a little different. I used that model as a starting point and adjusted the dimensions to fit the Designer mouse. Adjustments made: Changed bottom radius Added slight taper to overall shape Changed from 6mm magnets to 4mm magnets (0.05mm of hole compensation needed to make them press fit)
