摘要
Osprey Hand是一款手腕動(dòng)力機(jī)械假肢，采用Blender制造，基于低聚內(nèi)飾和原始Raptor手部的堅(jiān)固部件，但現(xiàn)在具有吸引力的整流罩和非常耐用且舒適的低調(diào)通用型護(hù)腕。
Osprey針對大規(guī)格尼龍單絲的使用進(jìn)行了優(yōu)化，可抵抗線性壓縮并產(chǎn)生很小的摩擦，因此具有出色的鮑登特性;拉動(dòng)電纜以提供彎曲并推動(dòng)以提供伸展。該裝置既不需要彈性裝置也不需要彈簧或任何機(jī)械延伸系統(tǒng)。
重型尼龍單絲通常價(jià)格低廉，可作為園藝師的修剪線，尼龍或橋梁尼龍3d打印機(jī)長絲，以及深海捕撈領(lǐng)導(dǎo)線。我建議釣魚線，因?yàn)樗�有各種厚度。通過接頭，單絲完全沒有磨損，所以沒有印刷塑料的“鋸切”。
彈性阻力是許多輔助裝置的主要缺點(diǎn)，因?yàn)樽枇�會降低裝置的握力。此外，當(dāng)彈性伸展裝置接近完全致動(dòng)時(shí)，彈性部件的阻力增加，因此使用者可能很難抓住小物體。而且，大多數(shù)彈性材料會迅速降解。減少或消除彈性阻力的設(shè)計(jì)是一個(gè)受歡迎的發(fā)展。
特別注意新的物料清單。 Cyborg Beast，原始Raptor和Raptor Reloaded硬件套件與Osprey不兼容。但是，Osprey確實(shí)使用與Gamma Raptor相同的硬件。材料套件和工具包應(yīng)該在不久的將來可用，敬請關(guān)注。
在這個(gè)版本中：
具有不同公差的Pin-and-Proximal套件（“A”是最寬松的;“D”是最緊的）可以輕松補(bǔ)償打印比例，擠出設(shè)置和熱膨脹的差異。在說明文檔中了解Peregrine的ABCD密鑰！
2015-7-14更新
Palm v.2.1拇指旋轉(zhuǎn)以更好地對抗手指。這影響了手掌模板，也進(jìn)行了更新。
更新2015-8-26
從近端趾骨移除支撐材料。如果你錯(cuò)過它，請告訴我。由于在重物提升過程中它是一個(gè)常見的故障點(diǎn)，所以在遠(yuǎn)端的鉸鏈會變大。
2015-9-16更新
我添加了一個(gè)新的護(hù)腕/手套。這更符合Osprey美學(xué)，并且它具有更易于移除的支撐材料。舊的護(hù)腕可能會成為Gamma Raptor設(shè)計(jì)的一部分。
更新2015-11-23
更新了bracer和palm，并刪除了舊版本。增加了3/4“三角形扣。增加了近端”鍵“，以幫助確定哪種近端公差最適合手掌。
更新2016-6-16說明已經(jīng)有了很大改進(jìn)，所以請看看。
替換近端和遠(yuǎn)端趾骨：改善機(jī)械性能。
更新2017-10-19
添加了一個(gè)可打印的bracer模板，可以很好地適應(yīng)大多數(shù)客戶。安裝后，如果需要，可以修剪任何重疊的皮革，但對大多數(shù)客戶來說，這是不必要的。
添加了與PLA更兼容的卡扣組。計(jì)算ABS的原始針腳更柔軟。所以他們很難在PLA版本中插入。這些PLA針具有更長的尖齒，可以更好地彎曲。
增加了D形環(huán)扣。這是松散編織尼龍織帶的良好安全封閉。
2017年10月23日
增加了針鉗和銷釘推動(dòng)器，以幫助插入和拔出卡銷。

Summary
The Osprey Hand is a wrist-powered mechanical prosthetic that was built in Blender based on the low-poly interior and robust components of the original Raptor Hand, but now sporting an attractive fairing and a very durable and comfortable low-profile universal-fit bracer.
The Osprey is optimized for the use of heavy gauge nylon monofilament, which resists linear compression and generates little friction, so has excellent Bowden properties; the cables are pulled to provide flexion and pushed to provide extension. This device requires neither elastics nor springs nor any mechanical extension system.
Heavy gauge nylon monofilament is generally inexpensive, and available as landscapers' trimmer line, nylon or Bridge nylon 3d printer filament, and as deep sea fishing leader line. I suggest fishing line, since it is available in a variety of thicknesses. Running through joints, the monofilament doesn't abrade at all, so there's no "sawing" of printed plastic.
Elastic resistance is a major drawback to many assistive devices, because resistance reduces a device's grip strength. Furthermore, as an elastic-extended device approaches full actuation, resistance from elastics increases, so that it may be quite difficult for a user to grasp small objects. Also, most elastic materials degrade quickly. Designs which reduce or eliminate elastic resistance are a welcome development.
Pay particular attention to the new bill of materials. The Cyborg Beast, the original Raptor and the Raptor Reloaded hardware kits are not compatible with the Osprey. However, the Osprey does use the same hardware as the Gamma Raptor. Materials kits and tool kits should be available in the near future, so stay tuned.
In this version:
Pin-and-Proximal sets with varying tolerances ("A" is loosest; "D" is tightest) Make it easy to compensate for differences in print scale, extrusion settings, and thermal expansion. Learn about Peregrine's ABCD Key in the instructions document !
Update 2015-7-14
Palm v.2.1 The thumb has been rotated to better oppose the fingers. This affected the palm stencil, which was also updated.
Update 2015-8-26
Support material was removed from proximal phalanges. Let me know if you miss it. The hinge on the distals was bulked up, since it was a common point of failure under heavy lifting.
Update 2015-9-16
I added a new bracer/gauntlet. This fits the Osprey aesthetic better, and it has easier-to-remove support material. The old bracer will probably become part of the Gamma Raptor design.
Update 2015-11-23
Updated bracer and palm, and removed the old versions. Added 3/4" triglide buckle. Added proximal "key" to help determine which proximal tolerance best fits in the palm.
Update 2016-6-16 Instructions have improved a lot, so please have a look.
Replaced proximal and distal phalanges: improved mechanical performance.
Update 2017-10-19
Added a printable bracer stencil that will fit most clients just fine. After fitting, any overlapping leather can be trimmed if needed, but on most clients that won't be necessary.
Added sets of snap pins that are more compatible with PLA. The original pins were calculated for ABS, which is softer. So they were pretty difficult to insert in PLA builds. These PLA pins have longer tines that bend better.
Added D-Ring buckle. This is a good secure closure for the loose-weave nylon webbing.
2017-10-23
Added pin tongs and a pin pusher, to help with the insertion and removal of snap pins.
