Hey guys
I'm trying to add fans to my geeetech prusa i3 but they use connectors that aren't standard for fans. I don't want to spend 20 on shipping just to buy their 40mm fans. Can anyone tell me what type of connectors these are and how to convert/adapt/ do something to use standard fans?

Although the plugs are JST connections, you can use plain hitachi/servo style connectors on the pins, just like for an Arduino. (The same type that are on the end-stop switches.)  They are not as secure, but they work.   Amazon sells a JST connector set for about $18 or you can buy the servo connectors at many places on line.   I basic wire crimp tool is all you need to install them.   I trimmed many of the wires on my printer and replaced the ends.

I believe they are called JST mini series... You will also need the pins and the crimping tool. You would be better off finding a more common style with the same pin spacing and just replacing them as the crimping tool alone is over 50 bucks.

That seems to be them. Not 100% sure. I ordered a 20 pack of leads and I'll just strip the fans and solder the leads on. I can't believe the crimping tool is that expensive but oh well. Thanks for the reply.
