Most Halloween prints that snap on the lawn were doomed on layer 1.

Tall tombstones and fence posts have a tiny footprint relative to height. A 6 mm brim and 3 perimeters will save more displays than a "better" file. Print PLA for indoor/porch. Switch to PETG only if the piece lives in rain.

If you are scaling past 120%, add a 2–3 mm mouse-ear on each corner instead of cranking infill. Extra plastic in the core does nothing for wind load. The first 20 mm of the base does.

I keep STL files and live printer repair as two separate checkouts. Files do not fix a clogged nozzle. A one-hour session does not include a model pack. Buy the problem you actually have.
