Hario Skerton Shaft Burr Nut Adjustment Socket For 6 mm Hex key

I didn't have any key to fit and loose the nut, so i designed one. It can be used with 6 mm hex key.
There are .1 mm tolerances for everything and the model compensates for elephant's foot, so you can up the temperature for higher layer adhesion. Print slowly and carefuly, as there's not much room for bigger tolerances.
