Did I mess something up while printing either the Gauge or the Insert? As for me its not sitting flush. The Gauge is about 32mm thick but the cutout in the holder is only about 28 deep
Might very well be. I got mine from Printables long before Makerworld (or BambuLab for that matter) was even a thing, so maybe the designer of the gauge changed something in between. Unfortunately I’m currently abroad for my job, so I won’t be able to test that for another week or so.
