The author remixed this model.
A quick'n'dirty remix of Knaudler's outstanding design. If you live in a rented apartment or simply don't want to drill holes in the wall, you can easily stick your Fritzbox to this bracket. I have onlymaximized the contact surface. With double-sided adhesive tape it should not be a problem.
A nice side effect: the model also fits on the Bambu Lab A1 Mini (180x180 mm build space) when rotated by 45°.
