Added a bunch of extra fans, thermistors and a chamber heater to my V0.2 and ended up using two of these bad boys to get it done. Easy to setup, install and get to printing.

Want to add some extra lights, fans or Thermistors? This is the perfect add-on for your Printer Kit. Plenty of extra headers and power connectors to turn your rig into a disco inferno! Turn up the fans to ensure even heat soaking, flash the lights to dance the night away, and monitor those temps to make sure you get it just right.
