Nút bịt lỗ hút bụi trung tâm (Central Vacuum Wall Inlet Plug)

The flimsy central vacuum wall inlet covers break off easily. When they do, you can't use other central vacuum inlets until you have something that won't get sucked into the vacuum to cover the hole. Enter this basic plug that you can insert into the hole. This plug will stay in place when the vacuum is not in use and will also allow use of the central vacuum from other inlets in the house. It is also easy to remove from the hole.

• I recommend printing with TPU or other flex filament, for for strength and also for sealing ability.

• Print with 100% concentric infill.

• Any layer height is fine.
