哈哈，为了给我几岁的小朋友带来良好的敲门习惯，专门为他做了这个啄木鸟敲门器，用手拉动绳索一下就会让啄木鸟在底座上敲一下。

让他在娱乐的同时也，学会进门前先学会敲门的礼貌习惯。其实也可以当做门口的门铃来或一个摆件来使用。

固定方式我用的3M 双面胶，确实很方便，也比较牢固。

打印件不需要支撑，拼接处也不需要胶水，唯一需要准备的是一根长点的绳子。

Haha, in order to bring a good knocking habit to my child of a few years old, I made this woodpecker knocker for him, and pulling the rope with your hand will make the woodpecker knock on the base.

Let him learn the polite habit of knocking before entering the door while entertaining. In fact, it can also be used as a doorbell or an ornament at the door.

The 3M double-sided tape I used for fixing is really convenient and firm.

The prints don't need supports, and the splices don't need glue, the only thing you need to prepare is a longer string.
