Folding Doors

Some of these doors always lie while others always tell the truth. You can't speak their language, so it really doesn't matter.

The first sheet contains doors to print, fold and use on your tabletop. The doors are 20mm wide and 30mm tall with a 15mm deep base.

Updated with a second sheet that also contains a row of secret doors.
