历史：
我们今年春天从上海收养了我们的儿子。
他有一个轻微的痉挛性脑瘫病例，使得他的身体左侧不能完美运作。
他的左手一直弯曲着肌肉紧张。我们需要每天多次伸展和进行不同类型的训练。
我有这个想法，但我没有任何3D设计经验。
但后来我的一个朋友给我发了一个链接来解决这个挑战，这给了我新的动力。
花了一些时间来学习一个软件程序和很多从头开始，当我得到一个正确的设计我打印，测试，有时不得不重做，但现在我明白了:)
所以这是我对Thingiverse #AssistiveTech Challenge的贡献
使用：
对于我儿子来说，这只手只是为了一个目的，伸展......但事实证明，他现在也可以把手握在他以前从未有过的直立位置。
这是一个巨大的奖金，它在玩的时候真的会帮助他。
hANDi将手伸向“上手板”，伸出手。同时它伸出手指。
在设计添加到“笔架”后，我现在必须添加到此部分
是的，与此同时，他得到了他能够画出的拉伸，这真的有助于他掌握运动技能。坐下来看看他用手臂取得的进展真是太棒了......太棒了!!!
手的其他目的是肌肉康复。弹簧张力的原因。
我希望这只手可以帮助其他孩子接受CP或某种手部伤害。
所以我确保做了设计，所以它可以在左手和右手使用;）
我还在环和手板之间增加了一个可选择的手臂，它具有20度的向上角度，可以更加伸展。
关于大小，我们的儿子已经4岁了，这个设计的指尖非常适合他...如果它不适合，只需缩小一点;）或者问我，我会帮助你它:)如​​果你使用Fusion 360我可以邀请你到项目文件夹:)
另外......我有一些融合选项来提取文件。我是新手，所以我不知道最好分享哪个文件扩展名？我见过有人上传.STEP文件。
你想让我这样做吗？
打印后，我在手臂环内侧和手掌顶部下方添加了一些柔软材料。然后我用Velcro收紧它。
我用弹簧和钓鱼线连接指尖。

最新的hANDi版本的新图片与新的手臂环和添加:)
新事物：克努特2
新的拇指支撑与不同的角度，我们的OT推荐我们尝试这一个:)
希望我的英语是可以理解的;）

打印设置
筏：是
支持：是
解析度：中高
腾空：50％
笔记：
（本节中有降价的某种错误，我试图通过为新行添加
来理解这一点。希望它得到修复）

易于打印的部件
使用支撑材料，臂环易于打印，宽大部分朝下。
同样的指尖，指尖朝上站起来......他们需要支撑材料。
两个臂，一个用于拇指，一个用于将环和板固定在一起，最好在侧面印刷，带有支撑材料。
使用支撑材料，手指板最好平放，手指浮动。
添加：笔架打印平放，就像它坐在手上一样。孔所需的支撑材料;）
我打印所有的0层高度，支撑材料和50％填充，使部件强大，但也许它不必那么高。
我使用“printrbot简单金属”没有加热床和糟糕的桥设置，所以有一个更好的打印机这些部分甚至不需要支持材料:)
其他需要的材料：
2个弹簧
6个M4螺钉和螺母
大约1米的钓鱼线和谷歌搜索钓鱼结;）


或使用电缆接线片锁定线，请在此页面上看到图像;）（< - 推荐）
下载我的设计Knut 2或Knut并在弹簧和手指之间使用：

一些柔软的材料放在里面，使其舒适。
我是如何设计的：

这是我设计的第一步。 就在睡觉前我们坐下来做了这个:)

我使用了Fusion 360，这是我做过的第一个真正的3D设计:)版本1.0

完整的hANDi及更新的部件，包括笔架...... 2.0版
YouTube和图片

这是我的多附件Knut的hANDi，在这里找到Knut：http：//www.thingiverse.com/thing:1075335

所有部件加上Addon pennhoder（旧手环）

用笔筒的hANDi

使用钓鱼线锁定

使用这样的锁..只需将线槽穿过并用钳子压在一起:)

随着新的手臂环！ 适合手臂更好，更舒适:)

Hitstory
We adopted our son from Shanghai this spring.
He has a mild case of Spastic Cerebral palsy that is making his left side of the body not working perfectly.
His left hand is bent with muscle tension all the time. We need to stretch and do different kinds of training several times a day.

I had the idea for this hand for i while but haven't had any experience in 3D design.
But then a friend of mine sent me a link to this challenge and that gave me new motivation.

It took some time to learn a software program and a lot of starting all over, and when I got a design right I printed, tested and sometimes had to redo, but now I got it :)
So this is my contribution for the Thingiverse #AssistiveTech Challenge

Use
For my son right now the hand was made for only one purpose, to stretch.. but it turned out that somehow he also can now hold the hand in a upright position he never could before.
that's a huge bonus, it will really help him when playing.
hANDi both stretch his hand out by pulling it up against the "overhand plate". At the same time it stretches his fingers up.
One thing I have to add to this section now after designing the add on "pen holder"
is that at the same time he gets the stretching he needs he can draw, and that really helps him with hit motor skills. It is amazing to sit down and see the progress he makes in using his arm.. amazing!!!

Other purposes for the hand is muscle rehabilitation. cause of the spring tension.
I hope this hand can help other kids to with CP or some kind of hand injury.
So i made sure to do the design so it can be used on both left and right hand ;)
I also added a alternative arm between the ring and hand plate that has a 20 degree upward angle for more stretch.

About the size, our son is 4 years old and the finger tips of this design is a perfect fit for him... if it doesn't fit, just scale it up a little ;) or ask me and I will help you with it :) If you are using fusion 360 I can invite you to the project folder :)
Also... I have some options in fusion to extract the files. I am new to this so I dont know what file extension is the best to share? I have seen some people upload .STEP files.
Do you want me to do that?

After printing I added some soft materials to the inside of the arm ring and under the plate that lays on top of the hand. Then i used Velcro to tighten it all up.
I used springs and fishing line to attach the fingertips.

Notes:
(some kind of error with the markdown in this section, I have tried to make understandable by adding < br > for new line.. hope it gets fixed)

Easy to print parts
Arm ring is easy to print standing up with wide part down, using support material.
The same with the fingertips, standing up with the fingertip facing up.. and they need support material to.
The two arms, the one for the thumb and the one that holds the ring and plate together is best printed on the side, with support material for the hook.
The over hand plate is best printed flat with the fingers floating.. using support material.
The add on: pen holder is printed flat down like it is suppose to sit on hANDi. support material needed for the holes ;)
I printed all with 0,2 layer height, support material and 50% infill to make the parts strong but maybe it doesn't have to be that hight.
I use a "printrbot simple metal" without heated bed and bad bridge settings so with a better printer some of these parts don't even need support material :)

Other materials needed:
2 springs
6 M4 screws and nuts
about 1 meter of fishing line and a google search on fishing knots ;)

Or use cable lug to lock line, see image a bit down on this page ;) (<--recommendation)
Download my design Knut 2 or Knut and use between spring and the fingers:
(image below)
Some sort of soft mateial to put on the inside to make it comfortable.

How I Designed This

This was the first step of my design. right before bed time we sat down and did this :)

I used fusion 360, this is the first real 3D design I have ever done :) version 1.0

Complete hANDi with updated parts including pen holder... version 2.0
YouTube and pics

Here is hANDi with my multi attachment Knut, find Knut here: http://www.thingiverse.com/thing:1075335

All parts plus Addon pennhoder (old hand ring)

hANDi with the pennholder

Make locks for the fishing line using

use the locks like this.. just thread the line trough and press together with pliers :)

With new arm ring! fits mush better to the arm and is more comfortable :)
