KitchenAid to Milescraft adapter 8

cults3d

Updated adapter between a KitchenAid stand mixer attachment hub and a Milescraft 90 degree drill adapter. There are two sets of changes: 1) To the square piece that fits in the KitchenAid hub. I expanded from 0.45 to 0.47"; this takes the slop out of the fit. (I believe the hub is designed as 12 mm.) I also chamfered the ends of the piece so that it's easier to get it into place. 2) To the cylinder that holds the Milescraft adapter bit. Multiple changes to try to prevent it from eventually wearing out and slipping. I added a 3rd set screw. I made the walls thicker. I added flat faces to the interior of the bit hole to try to match the bit shape more closely. Works with: https://cults3d.com/en/3d-model/tool/kichenaid-adapter-bearing-housing (But the bearing isn't critical to have for many applications.)
