Ender 3 CR20 Fan Shroud
thingiverse
A must-have upgrade for your Ender 3 or CR20 Pro - the Fan Shroud. This clever design features a mount specifically for the BL Touch, making it easy to integrate into your existing setup. The fan shroud consists of two parts, which are printed with minimal supports and about 40% infill. By utilizing the stock fans, this upgrade directs airflow more efficiently towards the heatsink, while also providing slots for heated air to escape.
