Unprintable tofu drainer

youmagine

Ever since I discovered how pressing/draining the water out of a cut-up block of tofu before marinating it can make all the difference, I've been eager to design something that will hold the tofu off a plate to maximize drainage efficiency. (Yeah, I guess you could say I'm a bit obsessive about this sort of thing). So here's the design in openscad. Why "unprintable"? Because the first version, with its numerous intersecting rectangles creating holes for water to drain through, results in a huge STL file which then produces G-code that prints poorly at all (a lot of long zigzag lines that will lift off the bed unless you've got everything perfectly tuned, and weak layers). So I came up with another version based on a technique I saw years ago (I'm sorry to say I didn't bookmark it) for making grids with infill. All I had to do was set the fill to 50%, specify no top or bottom shells, and voila! There was a nice, even grid in the g-code.
