This is a strainer for my bath plug hole (bath_strainer)
bath_strainer1 is a revised version... (see stl files)
I have made a recessed hole in the middle of the strainer to aid water flow, I also added some more holes.
I made the holes 2 mm but I may need to increase to 3 mm...
Still a work in progress but works with regular cleaning :)
It has an outer diameter of 70mm and an internal diameter of 43mm.
The outer rim is 1 mm thick, overall it is 6mm thick
The holes are 2 mm.
This is my first design...
Maybe some adjustments are necessary...
I will update after some testing :)
