(4 styles) fan duct with dust filter for the Elegoo Neptune 4 Plus

Based on the great design from @DirtyBady_669567, I have created a total of four customized versions:

- a slightly longer version for a calmed intake (for attaching an external filter as in the original)
- a slightly longer version for a calmed intake with rounded edges
- a turbo-style fan duct with a long intake
- a turbo-style fan duct with short intake

I expect a slightly better airflow and slightly quieter intake noise.

Dust filter
If required, a filter (as in the original model) can also be attached to the flat version.
I have attached two layers of fly screen to the “turbo-style fan duct with short intake” from behind with superglue, but you can also use hot glue.

Print
Please print with 0.2 layer height or less or use adaptive layer hight. Brim and supports are recommended.

Installation
All versions fit plug'n'play. Function and air flow are not affected or impaired.

Do you like my work? I would be very happy if you would support my work on Ko-fi.

Rounded some edges, make some enlagements or added a turbo-style fan duct
