I broke the Heat Break and Nozzle on my Chimera when I over tightened them. First I broke the brass nozzle with the threaded part jammed in the heater block. I though I could reuse the heater block first by removing the heat break and the heat break also broke. I am now out of pocket for a new replacement set but it seems that there are no more spare parts for Chimera or am I missing something? So the heater block and nozzle are the same as that from V6? That's fine but what about the Heat Break? Is the Heat Break the same as that of the Cyclops? This raises another question. Is Chimera obsolete and if the spare parts of Cyclops are still available does this tell me that Cyclops is better for dual extrusion than Chimera?
