Toilet Hinge

I designed this Toilet Seat hinge so I wouldn't have to buy a whole seat.
You will want to print for strength in the right directions. For starters I recommend 100%Infill. I also included pictures of how to set the models for printing. For the base and the end piece each layer needs to print the entire circle of the ring. The Axel needs to be printed such that the entire length of the axel is printed with each layer.
The screws were #6 5/8" wood screws.
Don't be confused with the different color pieces. In middle of the project I decided to see how well the glow in the dark white ABS would do in the bathroom at night. I used images of the black pieces where I felt it would highlight the point better like how the layers should flow during printing.

Good luck!
