Description

This is a simple hook I designed to hold my backpack. The hook has a circular mounting hole, allowing it to be attached to a wall or other vertical surfaces without using screws or nails. The hook's end is slightly curved to prevent items from slipping off. 

I can't say with precision the weight it can hold, but I use it to hold my backpack with an iPad and a few other objects inside. 

Step file is included, if you want to play with the dimension of the model.
