For an upcoming project I need a set of meshs. I looked at buying one, but couldn’t see anything that suited my needs and was cheap. So of course, I designed and printed my own.
I designed it in OpenSCAD which makes it really easy to change the size/mesh. They are stackable, so you can put as many as you want on top of each other. It took a couple of prototypes to get the design coming out nice, but the result is really good. I tried it out with some salt and it worked perfectly.
You can get the models and scad file on Printables or Github.
