OPAM (One Piece All Metal) Water-Cooled Hot End

Hi Fellow Reprapper,

I have just launched my indiegogo campaign on All Metal Hot End (Water-cooled) as per:
OPAM (One Piece All Metal) Water-Cooled Hot End




In summary, the distinct features of my hot end design:
1) A truly One Piece All Metal (OPAM)design (where nozzle, heater block & heater cartridge is combined into one single piece of stainless steel) to remove any filament jams
2) Water-cooled for high temperature extrusion of up to 350°C
3) Jamless printing of ABS, PLA, PC-ABS & much more!
4) Compact design (Lightweight of 40 grams)

Please review/feedback and contribute if it interests you!
Thanks,
