# 制作注意|Production Tips

## 1.0

### 1

在制作 **B8c** 零件时，请注意需要给圆台内部支承（ **B15** & **B16** ）预留一定空间。可能需要在其中一个齿上切缝或将该齿直接切除。

When making **B8c** parts, please pay attention to the need to reserve a certain space for the internal support (**B15** & **B16**) of the round table. It may be necessary to cut a slit in one of the teeth or cut the tooth directly.

当然，你也可以不采取图纸上 **B8c** 零件的切割方式。你可以参考下图进行切割。

Of course, you can also not adopt the cutting method of **B8c** parts on the drawing. You can refer to the figure below for cutting.

> 采用这种切割方法的其中一个好处是，无需用胶水粘贴燃料贮箱和圆台下底，这使得后续安装太阳能电池板变得更加容易。
>
> One of the advantages of using this cutting method is that there is no need to glue the fuel tank and the bottom of the round table, which makes the installation of solar panels much more easier.

### 2

需要忽略或裁剪 **B8b** 部件。

The **B8b** parts need to be ignored or trimmed.

可以忽略制作难度较大的 **C5b/c** 部件。

The **C5b/c** parts that are more difficult to make can be ignored.
