Mushroom Trio STL Files, 3 Decorative Mushrooms and Silicone Mold Making Set, Cottagecore Decor

Create spotted mushroom decorations with this mushroom STL set for 3D printing and silicone mold making. Rounded caps, raised spots and gently tapered stems bring a woodland, cottagecore feel to your decorative projects.

Print the original models for display, or use the master base and mold-box components to prepare your own silicone mold for casting.

DIGITAL FILES ONLY
No physical mushrooms, printed parts or silicone mold will be shipped. A 3D printer or printing service and suitable slicing software are required.

WHAT’S INCLUDED
• Original mushroom model files for direct 3D printing
• master_base.stl — three mushroom masters arranged on a shared mold-making base
• mold_box_part_01.stl — first mold-box section
• mold_box_part_02.stl — second mold-box section

The shared master base is a production tool. It is different from the separate finished mushrooms shown in the lifestyle images.

TWO WAYS TO CREATE

1. PRINT & FINISH
Prepare the original models in your slicer, print them and finish them in your preferred colors. Create decorative shelf accents, tabletop displays and woodland-inspired arrangements.

2. MAKE A SILICONE MOLD
Print the master base and mold-box sections. Prepare the surfaces, dry-fit the components and secure the assembly before pouring suitable mold-making silicone. Follow your silicone manufacturer’s instructions for compatibility, release agents and curing.

Depending on your silicone and casting materials, possible projects include plaster, gypsum, resin and mineral-based decorative casts. Silicone and casting supplies are purchased separately.

MOLD-MAKING COMPONENT DIMENSIONS
Approximate overall dimensions when imported in millimeters:

• Master with base: 124.94 × 69.33 × 52.50 mm
• Mold box part 01: 67.93 × 77.14 × 59.45 mm
• Mold box part 02: 59.01 × 77.14 × 59.35 mm

These are tooling dimensions, not the dimensions of each individual finished mushroom. STL files do not store units; check the import scale in your slicer.

PRINTING & SCALING
• Confirm that each component fits your printer’s build volume.
• Choose layer height, walls, infill, temperature and speed for your printer and printing material.
• Inspect the cap overhangs and determine supports from your chosen orientation.
• When resizing the mold-making assembly, apply the same scale factor to all matching parts.
• Test the fit before printing a full production set or pouring silicone.
• Sand, fill or seal the master as needed; its surface finish will transfer to the silicone mold.

Print time, material use, detail and fit depend on your equipment, scale and settings.

COLORS & FINISHES
The lifestyle images show illustrative finished examples. STL files contain geometry only: painted colors, stone-like finishes and styling accessories are not included. Your results will depend on printing, casting and finishing choices.

BEFORE ORDERING
This is a digital project for makers with basic 3D printing and mold-making knowledge. Please contact us through Etsy if you have questions about the files or intended workflow.
