3M Command Strip Hanging Anchor

Acts as a simple anchor to tie strings to a wall without needing to drive nails into it. Uses large Command Strips, allowing you to hang heavier loads like a fabric canopy (which works great in combination with other tarp clip designs on Thingiverse).

Keep the weight of what you're suspending in mind, and remember that Command Strips or similar adhesives are designed to hold loads parallel to their long axis - you'll likely have a lower maximum weight since the tension in any strings you attach to the anchor will act perpendicular to the surface you're anchoring to.
