leaf separator for 40mm drain

Needed a leaf separator for my ACD Greenhouse drain. There are two gutters on each side with a 40mm drain to my water storage. But all the leafs will fall trough it. So I made this separator that fits in the drain/gutter.
You still need to clean the gutter, but no leafs will go in to the water storage any more.

You can scale it up if you have a different size.
