Airduct for Micromake C1

Airduct for Micromake C1, I use small turbo-like fan as nozzle fan. This thing require support material for printing, while I have do my best to prevent high slope. I built this to solve the warping issue inducted by thermal stress by cooling everything down. If your printer weren't under this condition, don't use it, because it may ends up in nozzle thermal error, feel free to take it, and enjoy it.
