Most Halloween prints look fine on the bed and die outside in a week.

The file is rarely the problem. Weather is.

What actually holds up on a lawn

• PETG or ASA for anything that sits in sun or rain

• PLA only if it lives on a covered porch

• 4 walls, not 2. A gust will snap a thin tombstone

• 15–20% infill is enough. You are not printing a helmet

Scale before you commit filament

A 200% yard skull is a different job than a desk bust. Print a 50 mm test of the thinnest wall first. If that snaps in your hands, scale up walls, not just size.

First layer is the whole show

Outdoor props are large. A bad first layer on a 10-hour print is a wasted weekend. Level, glue stick, and watch the skirt. If the skirt is trash, stop.

I design these files for hobby printers that sit in a garage — not industrial machines. If your printer is fighting you (clogs, bed, first layer), that is a machine problem, not a file problem. Fix the machine first, then print the haunt.
