This is a bar for Frigidaire FFTR1821 door shelf. Ours broke after 2 years so I design a replacement. It's a bit deeper to reduce the stress on the bar when storing oversized jug (in our case soy sauce).
Should fit 30" fridge with the same side fixation.
Printed in PLA and work great.
To assemble, you need 4x M4 insert + 4x M4x10 screw (8mm or 12 works but are a bit long / short). I also recommend using 4x M4 washer.
