The P1S even with the chamber fan gets warm and I was getting clogged extruder on long prints with the AMS. I wanted way to add a bit of cooling without leaving the door open when printing PLA. I'm a Tron fan, so I went with a black and blue circuit theme. You only see the circuit theme though when you raise the top glass as the top glass has a black border. I included a kick stand that you just insert into the riser that also click out of the way.
