。
编辑20/03/2014:添加身体的“对生拇指”版本。
编辑24/01/2015:添加一个热成型手套，可以在PLA中平压打印，轻轻加热成型。
编辑15/12/2014:增加了手掌区域宽而标准的热表单网格。非常有用的“拇指祝福”版本，在那里，维可牢附件变得更加困难，试图通过一个拇指通过手掌口袋。这是thermoform PLA的一个很好的例子:http://www.thingiverse.com/thing:403001
编辑18/09/2014:增加了一个“更宽的手腕拇指指腹”版本的手部。
编辑08/09/2014:添加了一个“拇指祝福”版本的手的身体，为那些仍然有一个可用的拇指。
编辑19/08/2014:上传了一个手的身体和护腕(短的和长的)，手腕尺寸宽10mm。
编辑12/08/2014:在柔性手腕铰链上增加“脚”，帮助增加胶面面积。
编辑29/07/2014:在全尺寸打印时，肌腱孔直径从2mm增加到3mm。帮助小比例尺印刷。

编辑08/07/2014:雕刻的插座更多，使其更大。
编辑07/07/2014:更新手指的基础铰链轮廓(7.stl)。这个新的轮廓，需要较少的力量关闭手指，但它的形状，以更好的帮助手指返回。

指令
印刷:
请参阅手掌插孔的尺寸图，并按比例缩放所有stls，以满足您的特定尺寸要求。有两个手模型，每个都有自己的手腕测量值，一个比另一个宽10毫米。
打印手身体与支持，除非你能打印成功悬垂。在45度仰卧时，可以在没有支撑的情况下打印这只手的身体。我想尽快尝试一下。
打印手指部分或垂直(如建模)或水平，再次，我使用支持。原来弯曲手的手指和铰链和这个完全一样。
打印铰链段没有支持。
根据PDF组装
铰链:
我为Filaflex建模，它比Ninjaflex和其他柔性PLA atm更有弹性。然而Ninjaflex确实工作，但它可能有点难组装，因此适合手的铰链可能需要一点额外的说服用螺丝刀等，也许有一些润滑可以洗掉，例如液体肥皂。我用Slic3r打印铰链，没有填充物，2或3周长(取决于规模)，这使他们很好，“海绵”调整如果你想要更硬或更灵活的铰链。手指底部的铰链以一定的方式安装，以帮助手指返回，请参见节图显示。任何问题得到基础铰链也可以帮助使用工艺刀和修剪一点点铰链或手的身体，YMMV。我发现以拇指为基础的铰链合页一个45度的攻击角度是最好的尝试得到一个角球首先。
你也可以用硅密封剂铸造你自己的使用铰链模具，我也包括在这里的完整性。
挑战。
这是打印没有支持。
加热成形版本:
打印在解放军。在平模式下打印后，用沸水或打火机/喷灯、热风枪等轻轻加热软化，然后将手臂弯曲至90度。一个好主意是在形成合适的挑战前在手臂上放置毛巾/布。在本例中，我首先打印了收件人手臂的扫描图。将铰链间距与打印手宽度匹配。显然，使用热量时要小心。
标准版:
有两个长度和两个宽度，以适应不同宽度的手腕。短版本使用1条尼龙搭扣连接手臂，但长版本有2条插槽。
将手套从“FFX - flexy -铰链手腕”上连接到手。还是在Filaflex上。用强力胶水把这些铰链粘好。
肌腱:
选择一根非拉伸的肌腱来获得更强的握力，或者选择一些更有弹性的来获得适应性的握力(想想拿鸡蛋)
通过指尖末端的两个灯丝孔给每一端喂食。灯丝的两端应该从指尖底部的相同孔中伸出(见图+照片)。打一个防滑结(左边系在右边，右边系在左边)，剪掉多余的一根。如果张紧正确，结应该隐藏在指尖的基础孔。将肌腱穿过手指的部分，从手的底部穿出。将适当的张力系在手套式张紧器上，然后用螺丝进一步调整。我建议使用M2.5mm机器螺丝，但这取决于你的打印质量。
手套:
我想“维可牢”式手套附件(见《电子人野兽》)是你最好的选择。打印“FFX - Bat_Connection”。在Filaflex和剪两个平行的裂缝在魔术贴手套。开槽的大小和位置应该是蝙蝠连接只是推动通过开槽和滑入两个渠道内的雕刻出来的手掌。这连接手套到手，看视频链接在主要说明。或者，你会注意到手掌内侧有4个凹陷，这些凹陷的位置使你可以安全地钻过手部，避开肌腱线，以“芝加哥更快”连接手套。
加热成形网:
我先在90deg弯曲了紧固件标签，然后把网孔拧进了手掌区域。这是棘手的，但与一些小尖自攻螺钉，你应该能够拧它的手掌区域。然后，我用气体打火机轻轻地、均匀地加热网片，直到它变得柔软柔韧，但不会太热而不能燃烧(强调)。一旦软了，我就用金属勺子背面向上展开网格，为用户创造空间，让他们的手滑到曾经凉爽的地方。几次加热后，你应该有一些适合收件人的东西。当手在手套里的时候，不要加热网片，等待它变得柔软但足够冷，然后在受术者周围形成网片。允许泡沫填充。

Summary
2nd iteration of the Flexy-Hand. It is now wearable so it can eat at the same table alongside Robohand and the Cyborg Beast
Extra features include :
Gauntlet attachment via Filaflex hinges.
Two length/widths of gauntlet available.
Sculpted palm socket.
Discrete internal tendon channels.
Adjustable tensioners.
Discrete glove attachment channels (or alternative "Chicago Fastener" method).
Left and right hand versions.
Scaleable.
Let's get this out there and e-NABLE the future to be better for some people. Bring on the improvements, re-mixes and modifications.
Please read the following article about it too : http://3dprint.com/8122/flexy-hand-2-3d-printed-hand/

This hand was printed on a new Witbox printer kindly donated by Recreus.
.
EDIT 20/03/2014 : Added an "Opposable Thumb" version of the body.
EDIT 24/01/2015: Added a Thermoform Gauntlet that can be printed flat in PLA and gently heated to be bent into shape.
EDIT 15/12/2014: Added wide and standard thermoform mesh for the palm area. Very useful for the "Thumbless" versions where velcro attachments becomes more difficult trying to route a thumb through the palm pocket too. This is an excellent example of thermoform PLA : http://www.thingiverse.com/thing:403001
EDIT 18/09/2014 : Added a "Wider Wrist Thumbless" version of the Hand Body.
EDIT 08/09/2014 : Added a "Thumbless" version of the Hand Body, for those that still have a usable thumb.
EDIT 19/08/2014 : Uploaded a Hand Body and Gauntlets (short and long) with a 10mm wider across wrist dimension.
EDIT 12/08/2014 : Added "feet" to the flexible wrist hinge, to help increase the glue surface area.
EDIT 29/07/2014 : Increased the tendon hole diameters from 2mm to 3mm when printed at full scale. To help printing at smaller scales.
EDIT 16/07/2014 : Put hole in base of finger hinge (7.stl) so that it can be inserted into hand body easier.
EDIT 08/07/2014 : Sculpted out the socket more to make it larger.
EDIT 07/07/2014 : Updated the profile of the base hinges for the fingers (7.stl). This new profile, requires less force to close the fingers, yet it is shaped to better aid finger return.

Instructions

Printing :

Please see dimension drawing of the palm socket and scale all the stls to suit your particular size requirements. There are two hand models each with their own wrist measurements, one is 10mm wider wrist than the other.
Print hand body with support, unless you can print overhangs successfully. It may be possible to print this hand body without support by leaning backwards at 45deg. I would like to try this one day soon.
Print finger segments either vertically (as modelled) or horizontally, again, I used support. Fingers and hinges from original Flexy-Hand are exactly the same as this one.
Print Hinge segments without support.
Assemble according to PDF

Hinges :

I modelled for Filaflex which is more elastic than Ninjaflex and other flexible PLA atm. However Ninjaflex does work but it maybe a little harder to assemble hence the hinges that fit into the hand body may need a little extra persuading with a screwdriver etc, maybe with some lubrication that can be washed away, e.g. liquid soap. I printed hinges with no infill and 2 or 3 perimeters (depends on scale) using Slic3r, this makes them nice and "spongy" adjust this if you want stiffer or more flexible hinges. The hinges at the base of the fingers are assembled a certain way round to aid finger return, please see section image to show this. Any issues getting the base hinges in can also be helped by using a craft knife and trimming a little off either the hinge or the body of the hand, YMMV. I find with the thumb base hinges a 45deg angle of attack is best to try and get one corner in first.
You can also cast your own with silicon sealant using the Hinge Mould which I also include here for completeness.

Gauntlet.

This is printable without support.

Thermoform version :

Print in PLA. Once printed in flat mode, gently heat either in boiling water or with lighter/blowtorch, hot air gun etc. to soften, then bend over the gauntlet's arms to 90 deg. A good idea is to place a towel/cloth over the recipients arm before forming the gauntlet to suit. In this case, I printed off a scan of the recipients arm first. Match the hinge pitch to the printed hand width. Obviously be careful when using heat.

Standard version :

There are two lengths and two widths to suit the different width wrists. The short version uses 1 velcro strap for attachment to the arm, but the longer version has slots for 2.
Connect the gauntlet to the hand by 2 off the "FFX - Flexy-Hinge Wrist.stl", again in Filaflex. Glue these hinges in place with a strong glue.

Tendons :

Choose either a non stretch tendon cord for a stronger grip, or something more elastic for an adaptive grip (think holding eggs)
Feed each end through the two filament holes in the end of the finger tip. Both ends of the filament should come out of the same hole in the base of the finger tip part (see section image plus photo). Tie off in a none slip knot (left over right then right over left) and snip off one of the excess strand. If tensioned correctly the knot should hide itself in the base hole of the finger tip. Thread the tendon down through the finger segments out of the base of the hand. Tie off at roughly the correct tension onto the gauntlet tensioners, then further adjust with the screws. I suggest M2.5mm machine screws, but it depends on your print quality.

Glove :

I guess a "Velcro" style glove attachment (see Cyborg Beast) is your best bet. Print off the "FFX - Bat_Connection.stl" in Filaflex and snip two parallel slits in the Velcro glove. The slits should be sized and positioned so that the Bat Connection just pushes through the slits and slides into the two channels in the inside of the sculpted out palm. This connects the glove to the hand, see video link in main description. Alternatively, you will notice 4 dimples in the inside of the palm, these dimples are positioned so you can safely drill through the hand avoiding the tendon lines for "Chicago Faster" connection of the glove.

Thermoform Mesh :

I bent the fastener tabs at 90deg first and then screwed the mesh into the palm area. This is tricky but with some small sharp self tapping screws you should be able to screw it the the palm area. I then heated up the mesh gently and evenly with a gas lighter until it becomes soft and pliable but not too hot to burn (emphasis). Once soft I then expanded the mesh upwards with the back of a metal spoon to create room for the user to slip their hands into once cool. A few re-heats later you should have something that would fit the recipient nicely. Don't heat up the mesh whilst the hand is in the gauntlet, wait for it to become soft but cool enough to be touched before forming it around the recipient. Allow for foam padding.
