Active cooling for up to 5 pololu style (A4988, drv8825, TMC2130 etc.) stepper drivers that are mounted in line. Allows me to drive my motors at much higher current. Requires regular 50x50x15 fan blower and passive heatsinks that are not wider than 9mm.

Fan can be fixed using a screw, but it should snap in place and stay there also without.
