FlyingBear P902 Printed Z Axis supports

While it's cool looking to have metallic supports for the z axis rods and motor, I think they are not really practical, you have five elements that have to be perfectly aligned in various dimensions between them. It's very difficult to have it properly aligned. So I designed this z supports that are giving me nearly perfect z alignment .

Its a little tricky to print.
The face thats touching the aluminum slot should be very flat, so i recommend printing this face facing up and use supports.
