Drian Cover Cup

This was out of necessity , really annoying when your shop is out of stock..

So this is a drain cover outer diameter 80mm cover 3mm thick and 48mm long, the neck is 58mm and 3mm thick.

I made a slight modification according to the original (also included ) to have more strength.inside edges rounded so it has more body to hold the cup.

The original always breaks on the row of wholes in a circle so this should break less easier.
