Sink and Disposal Strainer

thingiverse

Yet Another Sink Strainer: Keep your measuring spoons and teaspoons from going down the disposal! And keep the bulk of the food from going down -- using the disposal for anything but small scraps is notorious for clogging drain and sewer lines. My friends wanted one or two each. I measured their sinks and found three common sizes. STL files are provided for those (3 in = 76.2 mm, 3 1/8 in = 79.4 mm, 3 1/4 in = 83.0 mm). In addition, the OpenSCAD source file is included to allow customization. For that, open it in OpenSCAD 2021.01 or later, use the Customizer Window to modify parameters as desired using F5 to preview, and when satisfied press F6 to render followed by F7 to save as STL. The handle can be removed, shortened, or lengthened. The curb around the outside can be raised, lowered or removed. The number of rows and columns of holes and the size of the holes are under your control. If printed in PLA and you pour hot pasta water over it, it may sag slightly toward the middle, but it's not too bad. PLA is not harmed by water (I have a running experiment with some pieces in water and they remain unchanged after 7 months). 03-Mar-2022 update: strengthened by increasing base thickness and handle girth. Also rounded off the knob by default.
