Winnebago Boldt BL mesh shower drain

thingiverse

I've tried different ways to pre-filter the shower drain in my Winnebago Boldt BL to avoid clogging up the shower drain pump filter, and thus far this is the best. This replaces the whole drain assembly. I used a heavy line of silicone sealant around the top perimeter, another extra heavy line around the mid flat bottom, and a dab of silicone on the flat nut underneath. Nothing in shower tub seems to be actually flat, so all the silicone should help it stay in place. The thread below fits the original nut and the 90 degree pex fitting directly. I printed items with threads at 0.1mm layer height to get the cleanest threads. I also used PETG simply because it's more temperature resistant and strong. I used two layers of fine 120 stainless mesh for the filter. I printed with the bottom threads on the bed with some fairly big supports to hold the wide/flat bottom. The flat bottom doesn't have to be pretty, and the silicone applied to it should help it cleanly mate to the shower tub.
