Made this to prevent the blower from sticking to my trousers and also to be able to cut the original mesh to allow more air in.

printed using pla on creality ender 3 s1 pro, standard quality 0.2 layer height. reduced the number of top and bottom layers t o2 for quicker print time. No supports.

Maybe print first 2 millimeters to test the fit. For me I made it snug on 4th attempt.
