Do you want to connect a 3 pin fan on a 4 pin header? if yes, you don't need any converter. 4 pin headers are backward compatible with 3 pin fans.

I want to make fan controllers. I am able to find everything locally except the 3-in/4-pin male female connectors. I am even finding good pots.

Okay. Try taking one peice of both male and female connector and header to an electronic store. Sometimes they have the stuff but don't know what it is called :) Else, you may use normal 4 pin female headers and salvage fan connectors.

You can use normal 3/4 pin male headers too.
