aration_a6.stl (accent issue when upload :-) )
Is an adaptation from one planned for A8. Very large to the point of not being able to see the beginnings of printing to make sure everything goes well. Another thing, I use clamps to hold a boroscilate glass and this piece took up so much space that the clamps were ejected when impressions on the edges
a6_fan_duct_v2_with_support.stl (better name no? :-) )
All the problems noted above are corrected with a somewhat revised ventilation so that the direction of the holes for the air flow arrives just below the nozzle. Definitely not perfect yet but I am satisfied with the result.
I add support because Slic3r is unable to make support only with buildplate. If you use Cura select "Touching buildplate"
a6_fan_duct_v3_with_support and gap.stl
It's the same than V2 with gap
For Cura use "Touching buildplate"
For slicer without functionnality ==> No support
