First print off MakerWorld a failure. Cockpit error?

OK, found a nice project in MakerWorld for a 10 plate holder. Downloaded the project and printed 3 of 4 plates and decided to do a partial assembly before printing out the final pieces. Oops, even thought I used the .3mf files as provided (except I changed the filament color), turns out the side pieces (front and back) are too short, the plates don’t even fit. Here’s a link to the project 10-piece Build Plate Rack. The plates are 256mm tall and the gap in the front/back plates are 240mm. Any ideas on what went wrong?

Many people have printed this. Was it accidentally scaled incorrectly when you sliced it?

Definitely cockpit error. After a few minutes of looking at the original MakerWorld post, I noticed that the front has a thinner top and bottom brace than the rear. I just need to turn the damn thing around 180 deg and all is fine. Embarrassing.

You beat me to it by about a minute. Your picture shows the back of the rack, and is upside down. The thicker horizontal serves as a stop to keep the plates from being pushed out the back.
