The STL files for the Jalousie, and to a lesser extent also the Plenum and Cartridge, are detected as having lots of objects in 1 file. For instance in Super Slicer, the "Split to Objects" or "Split to Parts" functions will reveal all of the tiny pieces that are too small to print
Are there any images, the jalousie has a lot of small gaps everywhere to force the slicer to print the walls in a certain direction in every layer, so I would expect some slicers to object.
