How to print

Click 3MF · multi-colour. Panels bigger than the bed come as a ZIP with one file per tile, numbered left → right, bottom → top.
In Snapmaker Orca use File → Import → Import 3MF/STL. Use Import rather than Open Project so your U1 printer settings stay.
The colours arrive as filaments 1–4. Load the matching filament in toolheads T1–T4.
Print flat side down, exactly as exported. With Limit overhangs on, no supports are needed.
Glue the tiles edge to edge, or onto a thin backing board.

Prefer plain STL? STL per colour gives one file per filament. Load them together and answer Yes when the slicer asks to load them as a single object with multiple parts.
