Spice shelf with holders

After the spice bottles had fallen into my head too many times when opening the doors, I decided to make something that keeps them organized and in place. A couple of tries later, it works pretty well. The first ones I made too thick "holder arms" so they broke. Next they were too thin and floppy. In the uploaded version I think I've nailed it pretty good, but it requires some care when slicing to get it working.

IMPORTANT!
Check the holder arms in layer view to make sure they are 100% fill
