Cardboard stripes cutter cat scratcher parametric

I made ergonomic cardboard stripes cutter. You need standard utility trapezoid blade (Stanley, Wurth, Dewalt etc.), other parts are 3D printed. Design is parametric, you can use Customizer to set desired values for slot width and cutting depth, or just use one of pre-made models. Mostly used to produce stripes of cardboard to glue them together and make scratcher for cat, but I guess there will be another uses. I suggest printing screw with lower layer height (like 0.12mm) to get smoother operation. Use with caution. Enjoy.
