Having covered a lot of the open areas and capping off places that can accumulate debris I noticed on the right side frame [opposite side of where the camera is mounted] theres an open hole in the frame. Debris probably won't reach it, but I figured why not make a cap for that in pursuit of a cleaner looking printer. Quick and Simple print, pops right in. Enjoy!
1/28/24 UPDATE - After getting my hands on a P1S I see there is a lip inside the hole unlike my P1P restricting the cap from seating properly. I've removed some of the material so now it will seat flush. Take a look at the pictures attached and print the one that works for you. With or without the lip in the hole.
