Need help making a lid for my juicer

I bought a Breville juicer. The pulp canister doesn’t have a lid. I want to 3-D print a lid. (I already looked online, and I didn’t see any files previously created for a Breville juicer pulp canister lid.)

Dimensions are shown in the pictures. Doesn't need to be airtight, just something that can sit on top of the pulp canister for a few days.
