High capacity humidifier

Initially I bought an 1.3l humidifier. As its boring to fill it up very 4 hours and it didn't increase the humidity enough, I decided to create an own one and put it in a 22l plastic box.

I didn't measure but I think it can humidify more than 15l without refilling. And the refilling is done just by adding water on the top, instead of put something out and screw off like on normal humidifiers.
One humidifier-part should blow 0.4 litre per hour, so 0.8 should be possible.
I am actually at 0.5-0.6, but I didn't optimize the height adjustment (which is easy with 4 screws).

For the swimming platform, I use cork. It would be also possible to do it just with air but i had no time to do much experimental stuff.

Boringly, my printer lost filament at the print of 3 swimming plattforms, so on the photos, they are not finished. I have fixed them with some wires.
