Moved into a house with a poorly maintained jetted tub. After multiple attempts at deep cleaning using various specialty cleaning products it was bad enough that my wife and I were considering a full bathroom remodel because the tub can't be removed without breaking tiles including the wall which ties into the shower and even the floor tiles.
I found NonDisjunctions Jetted Bath Tub Plugs which worked beautifully for the tub jets, but my drain/inlet had 2 screws instead of one in the center, so I made a new/separate version of his tub-mesh-drain-cover-v1.
I also had an air inlet for the jets that had a rather old and discolored, my wife asked me to make a cover for that as well so that we sealed the whole system up and so that it all matched.
The author remixed this model.
