I stopped buying “print-ready” props after the third tombstone that needed 4 hours of repair in the slicer.

The usual problems:

• Modeled for resin, dumped as STL, never printed on a 220mm bed

• No elephant-foot compensation, so the first layer mushrooms and the whole piece leans

• Walls too thin for outdoor PLA, so they snap the first windy night

• Orientation that looks fine in the viewer and warps the second it hits a cold garage

Print-ready, for prop work, means: first layer tested on FDM, oriented for a standard hobby bed, walls thick enough to live outside, and a brim where the piece actually needs it.

If you’re building a haunt this year, check the bed before you check the file. A crooked mesh will ruin a perfect STL. A bad STL will ruin a perfectly leveled bed.
