Aluhotends V2 - the next generation

here is the next generation of ALUHOTENDS

from the left -  mk2 clone jhead for sizing  1.75 cartridge version 1.75 resistor version 3mm resistor version 3mm cartridge version experimental deltabot lightweight version

1.75mm and 3mm - i have bowed to pressure to produce both sizes, however certain features in the future for things like the ultra short meltzone might not be as easy to produce as the 1.75mm versions

resistor and heater cartridge versions - some of us prefer heater cartridges some of us prefer wire wound vitrious resistors, both have their place, there is now two different heater block styles to suit them both

cold side is now shorter and lighter - give about the same z height as a jhead

the experimental delta bot version - this is a very experimental hotend currently weighing only 19 grams I'm looking to reduce the weight even further, this one by default with have a pushfit connector in the entry hole and will only be for 1.75mm filament, the meltzone on these i am looking to reduce to less then 7mm and a 2mm diameter space all the way down to the bottom, this should allow near retractionless use which would be perfect for bowden tube setups, currently this one is not up for sale yet
