Simple wrench key holder
Key holder in the shape of Wrench. While slicing, rotate the model 45 degree and turn off skirt or brim. Fairly simple print which requires no support.
Additionally you need to purchase 5 Screw Hooks (½ inch) and screw it in the 5 holes as shown. Attach it to the wall using 2 countersunk screws.
