Description

Ever since I learned about pressing/draining the water out of a cut-up block of tofu before marinating it, I've been wanting to print a thing to hold the tofu off a plate to maximize drainage efficiency. (Yeah, I little obsessive, I know). So here's the design in openscad.

Why "unprintable"? Because the first version, with many, many intersecting rectangles to create the holes for the water to drain through, creates a huge STL which in turn leads to G-code that does not print well at all (lots of long zigzag lines that will come up off the bed unless you have everything tweaked just right, and weak layers).

So I made another version based on a technique I saw years ago (my apologies to the originator for not bookmarking) for making grids with infill. I just set the fill to 50%, specified no top or bottom shells, and presto! there was a nice, even grid in the g-code.

Materials and methods

- clear t-glase or other food-rated filament
- 0.75mm or equivalent nozzle
- openscad with rounded-box library
- custom slicing profile with 50% rectilinear infill and no top or bottom shells
