Parametric tramming squares

I love watching Filament Friday, and I love those tramming squares.

I wanted bed leveling/tramming squares for my CR10s, didn't immediately find them for my bed size, didn't want to copy/paste g-code, and didn't want to incur the tedium of sketching it up for my desired dimensions.

Also, someday I might want to make different sized squares, but I won't want to change the dimensions of the lines by scaling them in my slicer.

I thought to myself: this is an excellent time to learn a little bit of OpenSCAD programming.

So, here's an SCAD file you can open in OpenSCAD and configure to have the size and number of squares that you want for your desired bed tramming print. Configure the line height/width to match your nozzle size, and you can use this for any size nozzle as well.
