Air conditioner vent insert. These inserts fit the aircon vents that hold four 175mm X 175mm inserts. I've provided two styles - one thicker and stronger, the other thinner which uses less material. Both are suitable for normal use.
I've also provided each model in three different file formats (STEP, 3MF, and STL). Simply choose the file you're familiar with, import it into your slicer, and print.
Much easier to remove & wash than the original (adjustable) versions. Any problems, please let me know.
