Screw Cover Plug for RV sink

I lost one of the rubber screw covers for my RV sink and doing some searching to buy a replacement I realized it was hard to find for someone in the US. Options to buy were on the high end of price scale and that was before shipping which equal or more than the unit price. Since the design is fairly simple I created a functional design that would print on my Mk3.9. I am sharing it so others in the same predicament can replace their lost screw covers relatively inexpensively and fast. I printed mine in TPU and at 90% infill. I used glue stick to ensure it stuck to the plate without a brim. Photo shows red TPU and I plan to print in black TPU for the final application. Red one worked fine and now I can have some on hand if others get lost.
