A quick print to keep the top lid of your Bambu Lab P1S open slightly when printing PLA. Easily attached to the lid handle and removal is just as simple for when you want the lid closed. Under 30 minute total print time (inc prepare time) in PLA using just 4m (13g) of filament. I don't have a X1 carbon but if it's the same then I assume it would work for that too.
