I keep seeing the same three failures on garden statues and architectural fragments. People blame the file. It is almost never the file.

1. The first layer is lying to you.

A 0.2 mm first layer on a slightly high Z offset looks fine on a calibration square and collapses on a 200 mm urn base. Paper-test the bed on a cold plate, then again at print temp. If you can slide a sheet with no drag, you are too high.

2. You are printing "stone" like it is a figurine.

Stone-look pieces want mass, not detail-at-all-costs. 0.2 mm layers, 15–20% gyroid, 3 walls. Slow the outer wall. Matte filament hides layer lines better than silk. Silk is why your "limestone" looks like melted candy.

3. You never printed the cube that came with the model.

If the 20 mm cube warps, the statue will warp. Fix retraction, cooling, and enclosure before you commit 400 g of PETG.

If the machine itself is the problem — clog, thermal runaway, layer shifts that settings will not touch — that is a repair session, not a slicer tweak. One hour, live, then you are done. Not a Discord that lasts forever.

Print the cube. Then print the piece.
