Quarto game with two grooves

This is a slight modification to "Quarto game + holder" by Matt0u

I really liked the fact that the groove was at the same height as the hole depth, which allowed me to change filament colours and get the groove AND the bottom of the hole an accent colour. Unfortunately his design only has one groove. So I added a second one for the tall pieces. This way, I could also change filament there and get the same bottom of the hole effect.
