My wife got an IKEA DUKTIG Play kitchen from our buy nothing group, https://www.ikea.com/us/en/p/duktig-play-kitchen-birch-60319972/
And wanted to adapt it to be a “real sink” so we bought one of these https://a.co/d/01rTgaw
The fake faucet only had 2 through holes and was held by small self-threading screws, and the pump was going to look ugly. So I decided to make a design I could print by inserting in to the bottom of the pump and be held by friction, and have a screwless mount for the through holes, while being able to fish the pump tube through, without kinking it.
Sharing the OpenSCAD design in case you want to use a different pump, hopefully the comments help you figure out how to change it.
