This is a hook that is designed to be secured to the wall by a removable adhesive tape with similar dimensions to the small size 3M command strip (S/P).  

The hook comes in 2 pieces.  The anchor is secured to the wall with the adhesive, and the hook slides over top to hold the payload and hide any excess adhesive tape such as the removal tab of the 3M command strip product.  

The anchors and hooks are not strictly compatible with any 3M product, and any adhesive strip's listed weight capacity may not be applicable to this surface or the hook itself.  Use at your own risk.

The print profile is oriented vertical so the hook load does not align with the layer lines.  It also has 100% concentric infill.  There is very little infill to begin with so the additional strength has minimal cost in speed or material.

If you slice it yourself, make sure the supports reach the tab that slots into the anchor.  Certain auto support algorithms may happen to miss this overhang by accident when slicing since it's so close to the other wall.  It's imperative that this  tab is well supported for proper fit into the anchor slot.
