Item 6 is the air conveyor for the CR-10 with dual Petsfang extruders. I made it in Techinit 5 because the PETG always tended to soften at the nozzles (which are very close to the extruder) when the fan was stopped. Made with the Techinit 5 product… a fairy tale!
Why 3D:
Not achievable by other means,
Why in Techinit 5:
If the fan is always on then even if that piece was made of PLA itself it would not have had any problems, but by staying several hours near the hot nozzle, a less temperature resistant material would have started to deform and therefore lose the shape needed to direct the air to the right place and in the right way.
