First post here (have been a silent observer for a while).
I thought that I would make my first post a useful one.
I have just published my version of a cooling duct/fan adaptor for the Snapmaker 3D printing module on Thingiverse.
See here… www.thingiverse.com/thing:3403426
It utilises the standard part cooling fan and redirects the air flow around the nozzle, directly onto the print.
I have been testing and using the part for a while now.
With the part fitted I have noticed improvements in my overhangs and thin walls.
Let me know what you think!
