Balco cooling duct - updated.

thingiverse

Cooling fan duct designed specifically for standard 40mm fans, engineered to be significantly lighter than traditional steel ducts and centered directly on the nozzle. Featuring Balco 3D Touch technology, this duct is optimized for precise printing with the fan face positioned on the bed. A new version has been added, featuring a smaller nozzle that provides a straighter flow path throughout the entire duct.
