duct w protector for hotend cooling fan 40mm

thingiverse

I designed this fan duct to effectively draw cool air away from the heating bed and direct it towards the fan. My goal was to keep the weight minimal, so I made the wall just 1mm thick. Additionally, a small grid is incorporated to safeguard the fan against any debris or loose objects that might accidentally fall in, or even more critically, human fingers. This design allows for support-free printing of the part if the grid is removed.
