This font is layed out on a grid, I was just thinking about using it for something:

Pichabs is the font, Picgrid is just the grid, and the rest are variations.

Or if you prefer for Mac, get package 0025 here:

Michael, this link may be of interest.

With regards to your idea of creating a "toolkit" for constructivist type design, I think it's important to be clear about what your aim is. Do you set out to exercise the creativity of type designers within extreme limitations? Or do you want to create a "toolkit" to introduce type design to newcomers as Briem has done in the site I linked above?

Perhaps there needs to be a balance between limitation and freedom, if you place extreme limits in the "toolkit", the resulting designs could be bland.

That said, I'm only a graphic designer with an unhealthy type obsession and I'm very interested in what type designers have to say.

Good luck!

If you've missed it, here's a recent thread re. favourite constructivist typefaces.

You might look at bitmap fonts. They are on a grid by default. Look at the Critique area for screen fonts here on typophile.

I had to think of OCR when I read it

Greetings: Steven

How about the entire Transitional category of type. Geometrically constructed on a grid, with precision and accuracy, could that not be what you are looking for? Pixel fonts might also be something too look at as a more recent development. Although, it seems you are referencing the Bauhaus, so try and dig up stuff on Renner, Frutiger, and the like.
