Summary

Improved version to mitigate THERMAL RUNAWAY errors. (Re-Mix from the original Prusa Fan Shroud)
Air-flow properties have been improved to aim slightly more downwards to the print object rather than blowing at the exposed heatblock/extruder.

Has similiar properties to the latest MK3S fan designs, but fits on MK2.5 and MK3 where the screw is attached/mounted from the front.

Its attachement part has also been strengthened so you can't that easily break it anymore when screwing it in.

Inside corners have been smoothened out to reduce unwanted noise.

Note: The small block is only there for proper printing support.
It is recommended to print without supports.

ASA or ABS is highly recommended.
PETG will most likely deform during usage.

Thermal Runaway Details

Please note that this only helps to mitigate the issue of blowing directly at the heatblock/thermistor.
It's still possible that the Thermal Runaway Error may be caused by something else such as:

1. Heatblock Thermistor Cartridge defective or not properly installed.
2. Ambient Temperature (too hot, too cold or fluctuating heavily)
3. EinsyRAMBO and/or its connector.
