Continuing on the journey of improving my OpenSCAD skills I worked up this parametric sink strainer for the slop sink in our basement. It’s a useful print because sometimes we clean dirty things in the sink (like muddy shoes) and keeping yard waste out of the drain is probably a good idea.
Here’s the sink drain in question. I just measure the diameter and depth of the hole and created a strainer that could fit inside.
It’s not a super snug fit so it’s easy to remove the strainer by just sliding it out when not needed.
You can also make a sifter, which is something I designed and printed before when I needed to sift the rocks out of some concrete.
You can customize the diameter, height, wall and floor thickness, and size and spacing of holes. I didn’t add the capability to switch to round holes versus square holes, but that may be an improvement in the future. There’s also no lip/edge like most strainers have, so maybe that should get added to the list as well. (Or you can check out Customizable Drain Strainer by fardog.)
You can get the .scad file from Printables.com – Parametric Strainer / Sifter. Just open in it OpenSCAD, set the size of things and render your object.
