About this 3D model

The long awaited 45° version of my concentrated airflow fan shroud is finally here. With this fan shroud, you can blow air directly at the nozzle tip, which improves small prints and bridges. The 45° angle allows for a smoother airflow transition into the duct, which should allow more air through with less backpressure. I printed the one pictured on an SLA machine (which i messed up a bit), but the part is designed to be printable on an FDM machine with no supports. Print in PETG or ABS for thermal stability.
