Hotend Assembly on rail

I'm working on a main project where I want to use 2 50x10 turbo fan with controlled speed for noise reduction, but it need extra time to redesign control box to add more circuitry.
In the meanwhile, even if there are tons of different printing heads I decide to share mine.
I would like a compact, light, silent and rail mountable printing head, but with small mods on printer.
less noise mean improve air flow that should allow to reduce fan speed.
small modification means you can use standard parts (fan and hot-end)


this is what my imagination was able to create. I'm still printing parts again and again to improve all details. I'll share asap when, I hope, a part will be printed successfully with the new head .

For every single part I will share printing parameter soon.
