Duck Dome valve cover
thingiverse
I received a Duck Dome as a gift but it didn't have a cover for the valve. So... I made one. This fits the valve on the 48"x36" pillow but I expect they all use the same valve. At the very least this will keep the bugs out. It is by no means intended to hold in pressure. Here is the Duck Dome -https://duckcovers.classicaccessories.com/catalog/product/view/id/945/s/rectangular-duck-dome-airbag-48-36-inch/category/27/ And you can remix the design in Tinkercad -https://www.tinkercad.com/things/5AMfCOd6wEH
