If your Performa 475 (LC475) lower case has a case of the sags, this stiffener should help bring things back into shape.

My ‘94 Apple Macintosh Performa 475 had a case of the saggy lower case. I designed this snap-on bracket to lift things back into shape without modifying the original case in any way. Should work on the LC475, too. I don’t have an older LC, LCII, or LCIII. I'm not sure if this will fit them. Maybe? Someone let me know, please.

In order for the snap-fit parts to have the best strength, I recommend printing this part on a 45-degree angle along its long side that's opposite of the bosses that protrude out the other long side.

Thank you, Megan
