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 own custom clamp according to your comfort and needs.
With this, people without fingers should be able to:
1) Use Touchscreens and Touch pads.
2) Brush their teeth.
3) Write and draw using pens and pencils.
4) Use Cutlery like spoons and forks.
5) Hold cups.
6) Hold shopping bags.
7) Use 4 mm Hex tool bits.
8) Use interchangeable screwdriver tools.
9) Cosplay as a pirate
Other Things needed:
1) 2x 5 mm nuts and bolts with washers to attach clamps to the arm
2) A small piece of Aluminium foil
3) A long Electrical wire
4) Tape
Optional: Padding of your own choice for the clamp.

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.
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:

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
