Most Halloween yard prints look great on the bed and die on the lawn by week two. Not because the model is bad. Because outdoor PLA is a different job.

1. Walls that are too thin. A 1.2 mm wall on a tombstone will crack the first cold night. I design yard pieces for 3 walls minimum and a 20–25% infill. If you scale a bust up to 400%, bump walls before you bump infill.

2. PLA in the sun. PLA will slump on a warm porch. PETG or ASA for anything that sits outside more than a weekend. If you only have PLA, print the piece as a shell and keep it under cover.

3. No drain path. Hollow props collect rain. One hole at the lowest point, 8–10 mm, facing down. Skip it and you get a water balloon that splits at the seam.

I built HauntForge around print-ready Halloween props for hobby FDM machines, plus a separate one-hour live session if the printer is the actual problem. Files and repair are not the same product on purpose.
