Gridfinity Folding Rule Holder

I have printed this model on my Ratrig V-Core 3.1 with an 0,4 mm nozzle. I Used the 0,28 mm layer height preset with 5% infill. The modell is plenty strong with these settings. I made two variants. One with cutouts for your fingers and one without them. I include the .step file so you can modyfy it for your needs.
