About this 3D model

all vent model is too big to me ,and I don't need LED strap , so I ,made one S shape vent for lower noise level (just a little) I use 1mm thick EVA tape to seal gap between parts , and under glass lid for now it have about 1mm gap between front and back parts, 0.5mm gap between side if you want make gap smaller you can edit step file to make it tighter
