Simple double hook for holding keys, bags, light garments, etc.  

Prints in under 30 minutes, no supports needed, and holes are sized for #6 countersunk screws (drywall or wood screws).  Option to print hook with two or one mounting hole.

I have not tested weight limit, but would assume this is light duty and dependent on what you attach the hook to.  The hook is likely stronger than a screw's connection drywall.
