译者按：一般情况下，办公室内都会面临相同牌子U盘一堆，然后谁那了谁的都糊里糊涂。贴纸标签用久了会蹭掉，除了自己DIY一些怪异风格的U盘外壳外，还可以“正统派”地打印容易辨识的外壳出来。话说这U盘外壳还有私人印章的功能呢。

Lets make a Personalized USB!
做个个人专属的USB吧！

Its Almost Christmas but do you have that gift for your special someone or a friend?Do you want a budget friendly gift from your old things?Well now this would be a perfect gift for anyone.
差不多圣诞节了，有否给特别人物或朋友的礼物呢？想花费不多，从旧物当中弄出个礼物呢？那这个将会对任何人都是个完美的礼物。

So again this small project will require 3D printing and some basic 3D modelling skills, you will learn how to do basic shapes, Chamfer, Fillet and shelling. more than enough to make realize how handy and convenient 3d designing/modeling. With this instructable ou will also learn some 3D printing tips/tricks
这小小的作品当中，我们需要用到3D打印和一些基本3D建模技能，你会学到如何构建基本形状、开槽、切片和去壳方法，足够让你懂得如何方便快捷3D设计建模了。同时在这个教程当中你也能学到一些3D打印的技巧窍门。

Things you will need
你需要的东西：

Caliper
游标卡尺

Usb "Any size"
U盘，任何形状均可

Hot glue
热熔胶

Xacto Cutter / Cutter
美工刀

Thats it the rest is up to you and your computer.
剩下的就取决于你自己和电脑了。

My suggested programs for basic 3D modelling is 123D Design.
我建议的基本3D建模软件是123D Design。（译者注：不光免费，而且消耗系统资源少，不需要过多渲染就能运行，反正现在大部分3D打印机也不是多色打印的。）

Step 1: Lets start!

一、开工！

Picture of Lets start!
20141220_132841.jpg
If you have old usb' around your house feel free to reuse it I one that needs to have a personalized casing
如果在房间里有旧U盘，尽管取用。我拿了一个，用来加上个人化外壳用。

Lets start of by taking it apart. Unlike mine it is glued inside so the casing had to be destroyed, some usb will just need some snapping to remove the casing but in some cases its glued inside take it apart carefully. use any tools available in your house.
就从拆开它开始吧。有些U盘不像我的那样，里面用胶粘住了，那样只能破坏外壳取出，它们的外壳是搭扣嵌套的。有些情况下，粘住的那种，只能小心拆开了。在家里只要有工具就能使用。

Step 2: Measurements

二、测量

Picture of Measurements

20141220_133308_HDR.jpg
20141220_133742_HDR.jpg
Before going on you'll need to test out the usb first. If its ok then better start taking down some measurements.
在继续前，你要试一下U盘能不能用。如果能，最好开始测量一下外观参数。

Use a digital caliper as this is said to be precise compared to an analog..... Sorry I dont have a digital caliper ok this thing is like 10 years older than me... Anyways measure the PCB board only.
使用电子游标卡尺，正如同字面意义那样，它比普通模拟量那种精确多了。（译者注：容易懂的话，就是电子和非电子的区别。）只是我这里没有电子游标卡尺，手上的家伙看起来比我老10岁……不管怎样，只是拿来测量PCB电路板而已。

Anyways as I got the measurements:
马马虎虎得到这些测量数据：

Length : 26mm
长度：26毫米

Width : 13.5mm
宽度：13.5毫米

Height/Thickness : 4.3mm
高度/厚度：4.3毫米

This is my second USB but its seems that its almost the same as the 1st one I made.
这是我第二个U盘的数据，但看起来和我第一个做的几乎一样。

Step 3: Start designing (paper)

三、开始设计（纸面工夫）

Picture of Start designing (paper)
20141220_134252.jpg
before you make your idea into a reality lets start by doing it on a paper.
在将你的想法实现之前，在纸上做一次。

I know it says bookmark but hey its a design right.. All you need to make that is a modelling skill, but lets make something simple. Like just type in the name. That is more than enough to make it personalized.
我知道这就是书签，严肃点，这是设计……咳咳，你需要的是一种建模技巧，但不妨让其简单化，打上名字就行，足够将其个性化了。

Remember the casing will need a 1.5mm thick wall this is enough to make the Led inside defuse and still show led working even when its covered with the finished USB cover.
留意一下，外壳需要1.5毫米厚外壁，让里面的LED显得黯淡些，但即使在完成的USB外壳盖上后，工作时仍能显示出LED。

Step 4: Get to the CoMpUtEr!

四、走起去玩（kai）电（jian）脑（mo）！

Picture of Get to the CoMpUtEr!
So lets begin modelling...
现在开始建模……

Remember the dimensions we wrote down? well now is the right time to use it.
还记得之前写过的尺寸吗？现在是时候用上了。

Length : 26mm
长度：26毫米

Width : 13.5mm
宽度：13.5毫米

Height/Thickness : 4.3mm
高度/厚度：4.3毫米

Since the width is 13.5 we will now write down a new set of measurements by adding .5 to.8 this is to make the usb fit nicely inside the USB cover. because (3D printing errors can reach up to .4mm so better put space so that the USB will fit nicely.)
因为宽度是13.5，我们现在要写出一系列新的尺寸，增加0.5到0.8之间，使U盘在外壳里能良好贴合。因为3D打印误差最大能达到0.4毫米，所以最好留些空间让U盘吻合。

So the new dimesions are
于是新的尺寸是：

Length : 26.5mm
长度：26.5毫米

Width : 14mm
宽度：14毫米

Height/Thickess : 4.7mm
高度/厚度：4.7毫米

using the 123D program we then make a box using the dimensions we type it in the new dimensions
用123D软件建立这样一个盒子，输入上面的新尺寸参数。

Step 5: Shell

五、外壳

Picture of Shell
3.png
Once you've done the box start making the shell. By doing so you must select Shell or (J) then select a surface
完成盒子后，开始加工成外壳。选择外壳（快捷键J），然后再选择一个面。

in the options select Direction- outside and type in the thickness 1.5mm then enter
在选项栏中，选择“Direction - outside”（译者注：就是让其向外延伸），输入厚度1.5毫米然后回车。

Step 6: Chamfer and Text

六、开槽和文字

Picture of Chamfer and Text
6.png
Chamfer
开槽
Simple as it is Select the edges to champer and then pres (C) for chamfer enter the distance 1 then enter
简单，只要选择需要开槽的边缘，按下快捷键C，输入深度1然后回车。

Text
文字

Press T on your Keyboard select a surface where you want to put the text and Type in your any word or name then enter
键盘上按下T，然后选择希望放文字的表面，敲入任何文字、名字后按回车。

Once done by selecting the text extrude it by 2mm
做完之后，选择文字，让其突出2毫米。

Step 7: Cover

七、盖子

Picture of Cover
Doing the same procedure just make the top cover
用上面相同的步骤来制作盖子。

Step 8: Export for 3D printing

八、输出3D打印文件

Picture of Export for 3D printing
8.png
After Extruding the text it should look like this so now that you are done
在延伸文字后，看起来就像图片那样，完成了。

Its time to export it in STL
是时候输出STL文档了。

Follow the image and you will know what to do.
跟着图片的指示，你就知道怎样去做。

Step 9: 3D Print it

九、3D打印出来

Using this website you can find your local 3D printing service
用这个网站你就能找到你的本地3D打印服务提供商。（译者注：记得输入英文，而且如果二三线城市快递就要等很久。）

Once you receive the printed parts you may now add a generous amount of hot glue inside after that insert the USB
当你收到打印好的零件，在插入U盘后，就在里面尽量灌热熔胶吧。

and your done! :D
接着就大功告成了。

I Forgot to Print my Top cover tho... well next time I'll order
似乎发现我忘了打印盖子了……下次再订。
