After opening a few ventilation holes for the refrigerator in the kitchen, I found that the effect was really not very beautiful. So I designed these vents to cleverly solve this problem. They can easily slide into the reserved holes, but due to the built-in anchoring mechanism, it's hard to pull them out easily even with force; however, with a little effort, they can still be safely removed.

Hole size:

Depth: 18 mm

Diameter: 67 mm

You can also adjust the model size according to your actual needs to fit holes of different specifications.

For example: a depth of 30 millimeters and a diameter of 100 millimeters.

The calculation method is as follows:

30÷18=1.667 → Scale the height to 166.7%

100÷67=1.493 → Scale both the length and width to 149.3%

If the proportions of the various parameters differ too much from the original design, the model may become deformed or distorted.
