Tuning tips
If the snap is too tight: try XY -0.1 mm (horizontal expansion) or 101% uniform scale.
If too loose: XY +0.1 mm or 99% uniform scale.
A tiny wipe of PTFE on pins can make it buttery.
Multi-color notes
AMS or manual color swaps supported.
For Bambu/Orca: enable wipe into infill to keep purge waste low.
