Tub Drain Cover

I needed a drain cover for our tub. I am always afraid i will lose my ring or anything else down the tube.
This is a modified version of the Shower/Tub Drain Screen by 3P3D. I scaled it to my drain size using Tinkercad
When i ran the water in the tub the force spun the original design on it's side. so i added 4 side walls to the design.
The cover fits drains 47mm.
