This idea comes from Klayton's “Bambu Lab Tool Head Cover Hanger", that should be working very well for the P1P.
I've reversed the hanger for the X1C tool head, so this small plastic piece supports the cover while I'm working inside the head.
Working on the cutter lever is obstructed, but it helps me a lot when I change the different hotends.
My print is in generic PETG, less then 5 grams of plastic and less then 30 minutes of printing time.
I hope to be helpful for somebody!
