To a RAMPs or similar board rather than direct to the arduino i hope :)

It's a fairly generic wire-to-board 0.1" (2.54mm) connector, many
manufacturers make them.

eg.
Molex C-Grid III series
Multicomp MC34 series
Amphenol Mini-PV
etc.

cpc/farnell etc have them listed as 'PC Connectors' - 'Wire to Board' -
then select 2.54mm pitch, 1 row, etc etc

dont forget to buy the matching crimp contacts, if your lucky the site
selling the shells will link to the crimps, if your unlucky you get to
read the datasheet and find the right one, they are not interchangable
on the whole so you have to get the right one.

the crimp tools are fairly generic and not too expensive, the crimp
contacts are usually all the same 'open barrel' type so its easy to find
a crimp tool for that.
