Print with the hole facing down with supports use something easy to remove as far as supports go. Hope you get some more use out of your Bidet! Model is slightly different than picture as model doesn't have open space between the direction indicator and the knob for easier cleaning.
This is a Greenco Bidet Replacement part for Greenco bidets and whatever also uses the same metal bit I guess.
The author marked this model as their own original creation.
