Float valve for hose

Sorry for my bad English , I use a translator ...

It is a float valve to be inserted directly in the water tank . Printing PLA ( ABS would be preferable ) Filling 35% No support . 2 types of levers : either to use a bottle ( Lever + Bouchon glued ) either with a threaded Tyge on which will be attached a float ( Levier + 4mm diameter rod + float)

I use a rubber ball stuck on piece parts such as seal ( red in the picture)
