Printed it in PLA with 0.15 layer height without support. Works for me so far. Downside in the current dimension is, that I cannot close the sink to fill my bathroom sink with water, as you may see in the last picture. For that I have another plug, I would use.
Use that sieve at your own risk. I am using the sieve to prevent hair from been sucked into the waste water pipe of my bathroom sink. So far it works.
Update 1: Updated the .stl-file with a newer version. I reenforeced the bottom, made the holes smaller and removed one circle of rows. This made the whole model stronger. Also the water can better flow through, and still the hairs will be filtered.
The author marked this model as their own original creation.
