I’m very sorry that I can’t provide a picture at the moment as I’m away on a business trip and don’t have the item with me. However, it’s a gear — a part from my child’s toy train. My plan is to buy various models of similar gears and see which one fits best. Thanks again for your reply.

As the title says, I’ve been wanting to try 3D printing a part recently. Its edge is damaged, but the seller says I have to replace the whole thing, which feels like such a waste. If there are any online tutorials available, please share them with me for reference. Thanks, everyone. Update：I finally decided to purchase the same type of material, haha, but I still welcome any related learning resources if you’d like to share them.

Thanks for the reply! I’ve decided to go ahead and get one in the end. Even though it’s just for home use, it’s still pretty frustrating to spend several hours printing something only for it to fail.

Great attempt! I’ve been wondering whether it’s really necessary to get a filament dryer — have you ever used one?

You're very welcome ，that helped me a lot.

Hahahaha, the puppy loves it—he really seems to like that big guy! I also recently noticed that the filament at home has become damp; the printed parts are coming out darker in color. I'm currently thinking about whether to buy a filament dryer. Looking forward to your feedback!

Yes, it is highly likely that when the wires were cut, they momentarily touched (created a short circuit), which damaged a small component on the printhead board where the fan connects. Since you've confirmed the fan itself works, the problem is almost certainly with the board that provides power to it.

Great post! I just printed a toy tank for my niece with PLA the other day, and she absolutely loves it. I had never considered adding motorized parts inside, though. She would probably be even happier if it could be remote-controlled. Thanks!
