actually, i take back what i said about that thingiverse model... after some investigation and a bit of coding in openscad, the stl files it produces have serious issues when sliced, so i wrote my own generator using the svg output from that online bahtinov creator, exported the outline to dxf in inkscape and imported and extruded it in openscad (with the borders generated from the imported dxf dimensions... works rather well IMHO. each radius has 2 3mm holes to pin the pieces together when in use.

this thing being 'robust' is an understatement.
