I needed to make an old toilet last just a bit longer lol. The plastic part that is screwed to the bottom of the tank that holds the flapper in place broke and I couldn't find a part that fit close by so decided to design my own. Its not the wheel but it works like a charm. I printed in PLA and then gave it a thin coating of UV resign to make it a littler more waterproof and stronger.
Prints with no supports. Print one main fix and 2 pins. May need a tiny bit of sanding for pins as snug fit but do fit in holes and glue in. Make sure to use washers etc as required. I have a washer both under and on top and have no leaking problems so far.
