About this 3D model
This is a TPU addition to Marwyn's ventilation model. It adds Hex TPU inserts that go in the holes. And a flat TPU insert for the covers. The covers have two options, one normal flat, the other is tapered. Make sure that the Hex inserts protrude just a bit to have enough pressure when the cover is put over but not too much that the magnets can't pull it back in place
