A month ago a guy kept on harassing me about 3D printing him a thing that can shoot projectiles. I didn’t know him (idk how he knew that I can do that for him), so I just made excuses for a week, but then I just printed him a toothpick shooter with some dull fake toothpicks. He was happy, didn’t hear anything from him, but after 10 minutes I saw him with a teacher and he pointed at me. The teacher came to me and asked if this thing was mine. I just said that I made it, but I gave it to that guy, and he just asked for my name. After I asked him why, he said that he didn’t do it, but he admitted it after everyone said that they saw him. And in class a few days later my teacher came to me and explained that I get detention and maybe even expulsion from school. After detention my parents could convince the teacher that it wasn’t my fault and I didn’t get expelled, but now he is harassing me every day at school with „Heeeeeey, how was detention?“ and stuff like that and making fun of me (he didn’t get punished for doing something with it).
So can somebody help me get revenge without getting in trouble?
