PS: I'm working on a v2 with less parts (only the useful ones), fixes and improvements to this design. Any feedback is welcome: https://www.thingiverse.com/thing:6917532

The core idea was to make it modular, self draining, short and useful for most people with little changes.

If your faucet is bigger or smaller than mine you just need to change that part, no need to worry about the sponge holder.

If you have less space between the sink and the wall, you can skip the middle row and it will work just fine.

If you have something more or different, just make the part you are lacking. The design is simple so it's easy to make (if you ask me to do it I might, just don't expect me to do it soon)
