Remixed Extruder gear removal tool to include modification KYZ_446301 made with clippers per the comments. This allows you to remove the gear without removing the nozzle.
16 min adaptive 3mf. Struggling with warping after just a few mm of height. Using PLA+ on P1S with 0.4mm nozzle. Standard Bambu PLA settings. Standard Bambu textured PEI plate. Plate re-cleaned on 3rd try. Running OrcaSlicer 1.7... because it normally works fine for me. Warping very unusual for me to see. Initially tried 5mm mouse ear then full 5mm brim. Looking at the slice there does look like a 1/2 width layer 1 gap between model and brim caused by tiny chamfer. Never looked that hard before so maybe normal? OTOH brims and mouse ears normally work fine for me. If anything, normally too hard to separate from model.
Switched to PET-G (because it is in the AMS) and can be sticky'er for me. 0.28mm Extra Draft, 15% grid, 2 wall/3 top/ 3 bottom (because.. my defaults). Worked, but again the brim seemed totally disconnected from model and when done the model lifted off plate without apparent connection to brim that stayed firmly in place. All a bit odd from my POV. Image is slicer result, brim on right and model . Grey is bed.
Anyway - thanks for the model. Added to my emergency supplies. :-)
