My wife wanted a shelf to hold something small and a hook to put her backpack when she gets home from class. I made this and it seems to hold pretty well!

Originally, I tried to print everything together as one piece using ABS but the print would fail when making the hook. As a word of advise, if you're making a wall hook turn the piece on its side to ensure it is as strong as possible. Also, if you print this in ABS make sure to add a brim on the hook, mine warped slightly and peeled up from the bed plate.

After printing all parts, to attached the cloud to the hook I used 1 M3 12mm screw with a 6mm heat set insert in the top of the hook. To secure the piece to the wall, I screwed a drywall anchor into the wall then screwed through the piece into the anchor. The caps are optional, but if you have no warping they should fit perfectly.
