Companies have finally got the clue that these heater cartridges need a bend in them. So they came out with this. This is a smart idea which should have been implemented in the first version. This will make wiring easier as well as keep everything out of the way and organized. They just started selling them online and on eBay the prices very from 5 to 20 dollars depending on voltage, wattage and supplier. I personally will be snagging one soon and if your already running one of these on your reprap. Let us know the good and the bad on these new cartridges.
