AquaOasis humidifier refill base

I used to use tap water for this humidifier, so it was easy to fill it up without a stand, but now I'm filling it up from a bottle which makes it less convenient, so I needed a stand to hold it upside down. I searched for a solution and couldn't find one, so I designed my own. Sharing it here in case someone else needs it. The STEP file is available if anyone needs to tweak it.
