About this 3D model

This is a dryer I originally designed for SodaStream bottle, but it can be used with any bottle with the wide-enough throat. A dryer is very stable and doesn't easily tip over even with a big bottle. It's also stackable, so if you have more of them, it doesn't take much space. This was my first 3D printing project and I made a countless number of prototypes. I'm testing this (final) design for a few months now and I don't think there's much more improvement I can do. Hopefully, you find this thing useful.
