This is a two part hook. It is meant to be printed in two parts, lying down, which allows the hook to be stronger had you printed it in one shot. If you print these parts at 150%: --the screw holes will accept drywall screws --the finished, assembled size is 3" long, 2.25" wide, and 2.25" high. --printing with supports helped a lot --the bevels are 45 degrees if you want to add your own implements to the base. The attached pictures show me using it for running my ethernet cable.
