Sink Knob for Children's Kitchen Playset

We received an American Plastic Toys (#11810) Cozy Comfort Kitchen playset as a gift a number of years back. It was missing a knob on the sink since it was first put together. We never bothered about it. Recently our youngest has been displaying some strong opinions on not being able to turn on the water of the play sink... Nevermind that only one knob was missing. It was time to fix this.

So here you are - a quick model of the missing knob. It was designed to match the existing knob, but has some unnecessary features. It doesn't seem to need the notch on the outside rim. And the sphere cutout to not waste so much material was a mistake. (I had to print it twice and i used supports the second time as a safety net. ...because you know... wall order is important! reminder to check settings when trying to squeeze a small part in between larger jobs with odd settings.)

Print in your choice of colors and materials. 0.2mm layer height; you might want supports (up to you). Print a red one and a blue one... (hot and cold)... or don't... maybe make them the same... your child might complain they don't match... Then again, just ask your child how you should print them. They might have additional strong opinions you were not previously aware of.
