Description

I wanted a dry bilge pickup that used a 1/4 NPT connection on top, so that I could use small push-to-connect fittings like those for RO systems with clear pvc tubing. I also wanted to use sponges that are made out of a longer lasting foam than "the standard sponge" so the size is a bit different: 100mm x 68mm x 25.4mm In addition, I've made a small lip around the base to hold the sponge in place, with a chamfer a few small holes. The chamfer and holes allow water to more easily come in contact with the sponge and be picked up, without having too much crud clog the sponge. The f3d file is parametric, so you modify it to suit your needs, if you use a different sponge size. The hole is parametric but the threads are not, so you will need to model that yourself if you need a different size.
