14cm lid for the "Ideal Waste System" of Ideal Standard (Model T00063501). Ours broke when the cleaning lady dropped a bucket on it, so time for a new one. We didn't really want to order a new lid as they cost about 70€, so made one myself.It's not perfect (I would've liked rounded edges) but it does the job and fits. The grey print was a test in low quality (with a lower slide count on the circumference). The red one is a higher quality print.
