Faucet Adaptor for Toddler Spout

We got these silicone faucet spouts to help our daughter use and reach the sink. Unfortunately the "universal" design wasn't so universal, and the silicone ring would not stay on the faucet aerator. The sink's aerator is a tad too narrow, and too small a diameter. So, I whipped up this little bushing thing, to give the faucet a little more gurth, and made a wider ring with a lip to ensure it stays on. Printed with PLA. The ring is a good pressure fit, nice and snug. ABS you may need to scale it
