After quite much searching after a suitable cooling solution for the stepper drivers i found those 15x15mm alu heat sinks and some small 10x10mm ceramic coolers to put on the underside of the board attached with adhesive thermal pads.
If the come loose i might add some epoxy to the edge or get some thermal glue.

Hey, I would also like to use those heat sinks for my stepper motor controllers. Could you post the supplier websites?
Updated post. I havent got so far in the build to try them out yet but they seem ok
Thanks, ordered all of them from Farnell. Best of luck with your 3D printer!
