Both plastic hooks off the Tesa self adhesive powerstrip hook broke off, but the powerstrips and the duo back plate remained on the door, so I remixed an existing hook and added the tesa mounting pattern to the back to replace the face plate with one that is more sturdy and only has one big hook instead of two frail ones.
Printed with PETG and in sideways orientation for optimum stability this replacement hook has held up very well so far. Ignore the slit at the bottom in the picture, I fixed the material thickness in the model.
The author remixed this model.
Added tesa mounting pattern for a double wide plate and changed shape slightly.
