The arm cuffs might be a way to restrict Harry's power in some fanfictions. It could be a plot device to create tension. For instance, if the cuffs were put on him by an enemy, he would have to find a way to break free or work around their limitations to save the day. This adds an extra layer of conflict to the story.
I've read 'Harry's Arm Cuff Adventure'. In this fanfic, the arm cuffs are a gift from an ancient wizard. They give Harry unique powers, like the ability to control certain elements. It's a really engaging read as it shows how Harry struggles to master these new powers while dealing with the challenges at Hogwarts.
Yes, there might be. The Harry Potter fandom is vast and diverse, and fans often come up with creative and unique concepts like this for their fanfictions.

One possible plot could be that Harry gets his metal arm during a battle with Death Eaters. The arm could be magically enhanced, with runes inscribed on it that give him new abilities like being able to sense dark magic from a distance. He then has to learn to control these new powers while also dealing with the prejudice from some in the wizarding world who see his metal arm as something 'unnatural' in a magical setting.
There are also some smaller, more specialized fanfiction platforms or communities that focus on specific aspects of the Harry Potter fandom. These might not be as well - known as AO3 or FanFiction.net, but they could still be a great source.

Well, it could be that he got it as a gift from some super - advanced ninja technology group in the fanfiction world. Maybe they saw his need for an extra weapon or tool during battles and decided to equip him with a metal arm.
