PRINTING AND COMPATIBILITY
Native colour 3MF projects for Snapmaker U1 and Snapmaker Orca. Open each 3MF AS A PROJECT to retain assembled colour parts and saved settings. Print flat back down, coloured face up. A compatible multi-colour printer, slicer, filament and experience are required. Other printers or slicers may need manual profile, colour and placement changes; universal compatibility is not promised. No Bambu-specific version is supplied.

SAVED SETTINGS
Complete Generic PLA starting profiles: 220 C nozzle / 65 C textured PEI bed, 3 walls, 10% gyroid and saved flow/cooling settings. Review profiles, colours, placement, adhesion and support needs before slicing.

PLEASE NOTE
CAD geometry checks have been completed, but these files have not been sliced or physically print, strength or stability-tested. Make trial prints before the complete set. Rounded edges and continuous backing do not guarantee against breakage or tipping. CAD checks do not certify a finished print as a tested toy. Inspect completed pieces for damage, sharp edges or loose details before supervised storytelling use with children aged 3+. Keep prints away from direct heat. Scarves, faces, animal details, wheels, barn and gate details are fixed relief on continuous backing. There are no moving wheels, opening gates or loose scarf parts.

Images are renders of actual model geometry, not photographs of finished prints. Overview panels show the designs rather than a shared-scale arrangement. Print-bed images show actual saved scale and placement on separate 270 x 270 mm beds, not sliced toolpaths. No physical models, display props, printer or filament are supplied. Colours and results depend on your setup.

AI DISCLOSURE
AI-assisted CAD tools were used in developing these model files. Listing previews are rendered from actual model geometry.

Personal and educational use, including your own classroom or nursery. Selling physical prints requires the separate PlayGreener Shop-Wide Commercial Print Licence for your business. Model bundles are purchased separately. Digital files must not be shared, given away, uploaded or resold, including modified versions. Keep your purchase receipts.
