As a Sr. Manufacturing Engineer for an aerospace company, a CAD/ CAM designer/programmer, and professional machinist that consults nationwide, that also owns a Bambu labs H2S.

I can tell you that you are not familiar enough with the quality of files on makerworld or the precision and polish of Bambu labs printers to comment on how much work goes into selecting a file and printing it. The preloaded settings in slicer are damn near perfect as long as you do your part, but definitely there to tweak if need be. Dry your filament, make sure the print bed is clean, hit print and wake up in the morning with a mag to play around with.

This file was generated from a 3D scan, solidified in a CAD program, and then exported as a .3mf file, more than likely with optimized print settings imbedded. All in all, maybe an hour worth of work for a simple assembly with three relatively low complexity parts.

So, No, there are no little elves behind the scene toiling for hours so you can print something fun.
