adamhill - Wow, are you using a 3d printer? It was always interesting to try to print something for the home on it. But you probably need to choose the ideal proportions. After all, the gutter guard must prevent leaves, branches, and other debris from entering the gutter. In addition, it protects the drainage system from blockages and deformation. Well, can you make it big enough as it is mounted along the length of the gutter and has a reliable fixation with fasteners? It seems that it is much easier to contact the gutter service https://www.maxima-aluminum.com; they will solve the problem and advise a high-quality gutter guard.
