i use autodesk fusion to make simple case model for my m6 pro,i make it a bit thicker for bigger battery. i also make it to fit with 80x80x25 mm fan, you can edit it to make it thinner. the one i found in website sold for hundred dollar which is very expensive. you can make it thinner to accomodate your netgear or make it for smaller sized fan. material can use petg or abs.
