About this 3D model

Angry after having to use a pair of vice grips to start my dryer for a few years, it dawned on me one drunken evening that I could easily model and print one. I whipped this out in about 5 minutes, printed it, and it slid snugly on, the first try. The only thing it is lacking is an arrow pointing the right direction (I just used a file and made one of the tips arrow shaped) I hope this is useful for someone else. Measurements: 45mm Outer diameter 6.2mm Hole size 5.1mm Slot width
