It's a small model of a floating faucet fountain. Like the name says: it's a faucet with running water, although it's seems to float and have no connection to pipes. 

 My first faucet was a little bit too big (see pictures), so I created a smaller one that will work with the small pump and is easier to print.

The pump can be bought at Aliexpress and I used the horizontal type with USB: [https://nl.aliexpress.com/item/33018143812.html?pdp_npi=4%40dis%21EUR%21%E2%82%AC%201%2C49%21%E2%82%AC%201%2C40%21%21%211.61%211.51%21%402103867617439650160536212eadaf%2167159561588%21sh%21BE%21712241629%21X&spm=a2g0o.store_pc_allItems_or_groupList.new_all_items_2007586117160.33018143812&gatewayAdapt=glo2nld](https://nl.aliexpress.com/item/33018143812.html?pdp_npi=4%40dis%21EUR%21%E2%82%AC%201%2C49%21%E2%82%AC%201%2C40%21%21%211.61%211.51%21%402103867617439650160536212eadaf%2167159561588%21sh%21BE%21712241629%21X&spm=a2g0o.store_pc_allItems_or_groupList.new_all_items_2007586117160.33018143812&gatewayAdapt=glo2nld)

Might do a bigger one, but then I will also need a more powerful pump and I will need to do some calculations for that (and I hate math).
