One of the limitations of the Wanhao D6 is the poor ventilation. So I designed a new left-hand side fan duct with a radial 5015 fan. There is a lot of improvement in printing quality.
What do you think about this?

One of the biggest limitations of the Wanhao D6 is the poor ventilation of the printed part, especially for materials like PLA and similar. I therefore designed an additional cooling system on the left side using a more efficient radial fan instead of a classic axial fan. Unfortunately, the D6 is not designed (very badly...) for an additional fan, it doesn't have space on the left side and so I had to compromise in this first version, but I intend to fix everything in the later versions.
