About this 3D model

Prototype for coupling the Kitchenaid stand mixer attachment hub to a Milescraft 1390 90-degree drill adapter. This piece failed fairly quickly, with the set screws getting forced back over their threads and no longer gripping the Milescraft shaft. But I think if you just screw the set screws directly into the tap holes rather than tapping the holes first the fit will be tighter and more long-lived. The newer model is very similar and has lasted longer so far with this approach. http://www.shapeways.com/model/510417/ http://absurdlycertain.blogspot.com/2012/04/kitchenaid-drill-adapter.html http://absurdlycertain.blogspot.com/2012/05/update-diy-hario-conical-burr-grinder.html
