Most yard prints die in the first 20 minutes, and it is rarely the file.

What I keep seeing on home FDM this time of year:

1. The printer says the bed is level. One corner is still off by 0.1 mm.

2. A 300 mm tombstone gets scaled down on a 220 mm bed, walls go thin, and it snaps at the first breeze.

3. No brim on a tall lantern. Garage draft knocks it over at 40%.

If you are printing haunted-yard stuff this month: split large props at the natural seam (base vs top), keep walls at least 1.6 mm after scaling, and run a 40 mm test cube in the same filament before a six-hour job.

That is the difference between a porch that looks finished and a pile of PLA in the bin.
