As recommended on the Bambu Wiki You should leave the P1S and X1C glass cover and door open to prevent heat creep causing clogs when printing PLA etc - but I did not like the way the door swings around during prints as this cannot be good for print quality.
Here is a holder for the glass lid that fits snugly onto its handle and matches my popular Door latch.
As requested I've added a longer and extra-long version too.
A small number of people have found it slightly too tight due to the tolerances of their printer/glass handle - if this happens to you print at 101%, don't force it on! You could also use the handle replacement version too which fits using the original handle screws: https://makerworld.com/en/models/456050#profileId-363795
