2 small component (drainage) drawing suitable for 3D printing

My business Alfresko Ltd makes aluminium glass rooms, see, www.alfresko.co.uk

To avoid problems we have decided to provide our own drainage solutions which are build upon the existing Flopast 68mm system.

I need a designer who can produce 2 x drawings for components that are compatible and used for 3D printing

They are very small and simple.

Component (1) is a leaf filter that sits in a flat botton gutter with a sleeve that fits into the internal diameter of the downpipe, which we estimate to be 65mm (see attached)

Component (2) is a collar that fits over the 65mm flange of a 90 degree bend.

I have done my best to represent what i want but can likely do better. Let me know if you need clarification.

We are not looking to spend a lot as this is a nicety not esential.

Thanks.

Ian
