Affordable Prosthetic for people without Fingers

thingiverse

This multipurpose hand prosthetic is designed for people without fingers so that they could perform some basic activities. While there are plenty of such projects online, they are mostly either too simple or are too expensive and too complex for cheap mass production. As an Indian, I have designed this especially for people living in poor countries where this prosthetic can be distributed very cost effectively by health agencies. The arm clamp is detachable so that you can make your custom clamp according to your comfort and needs. Note: The model I printed came out quite bad because of my broken printer. I have made quite a lot of design changes. However, I haven't had the time to test those changes. So it would be amazing if anyone could print this and give me some feedback in the comments. With this, people without fingers should be able to: Use Pens and Pencils Use Cutlery Use Toothbrush Added features: Hold cups Hold bags Use touchscreens Use 4mm Hex tool bits and interchangeable screwdriver sets I got the inspiration after stumbling different assistive devices on Thinigiverse . I am also uploading a version without the cup holder. Print Settings Printer: Self Made Rafts: Doesn't Matter Supports: Yes Infill: At least 20% How I Designed This This arm is a mixture of many simpler designs available on thingiverse. I have tried to add as many as functionalities to this one arm as possible. I used CATIA V5 to model this arm. Additional steps Making the stylus In order for the stylus to work, it should be conductive and be connected electrically to your body. There are many ways to do that which can be found in this wikihow article:http://www.wikihow.com/Make-a-Stylus I will describe here the simplest way and my favourite way to do it: 1) Take a small piece of aluminium foil. 2) Attach it with a piece of wire. 3) Wrap this around the stylus tip and stick it with tape. 4) Extend the wire to the clamps. 5) Add a small piece of metal to the other end of the wire. 6) Whenever you want to use, attach this metal piece to your body and the stylus will start working
