Refrigerator Temperature Control thing

I made this In Sketch Up 2022.
I have found the sketch up does not export models well Hopefully this works.
I have included the Sketch Up file for the part.
There's a motor that turns this and this pushes a flap that opens to allow air from the freezer into the refrigerator side. The two open slots are for two limit switches.
I printed this with 4 line count for the shell.
