Most Halloween yard STLs look fine on screen and fail on a standard FDM bed.

Split tombstones at the base. Print the spike as its own piece. 0.4mm nozzle, 0.28mm layers is enough for props viewed from the sidewalk. PLA is fine on a porch. Anything that sits in October rain wants PETG or a cheap outdoor coating, not a reprint after the first storm.

That constraint is the whole product: print-ready haunt files, and a separate 1-hour remote session if the printer is the blocker. No subscription. The files are not mixed into the support hour.
