As you may understand, the name "8-in Printed Coaxial Hotend" is a bit of a mouthful and doesn't roll off the tongue or anything. More importantly, if this actually becomes a new class of hotend, then the name would be too generic; it would be like a project called "Dual Extrusion Hotend" or "Large Gear Extruder". I was never shy about the syllable count, and something called "The Enraged Rabbit Carrot Feeder" exists.

Well my mind was just idly thinking and it connected the dots with other name styles in the industry, such as:

• Slic3r: A 3D slicer name that is supposed to look like "slicer"
• Construct3D: 3D printer company with the play on "constructed"
• SLAminator: SLA 3D printer with washing+curing built in

The end result is the name suggestion Coaxial8tor that is said as "coaxialator" and uses the number 8 because it has 8 inputs. I think it's a fitting name considering how complex the inner pipework is and how printers with more than 4 extruders are few and far between currently, thus a hotend that does double that is quite... extra... and should have a name to match.
