Compass Rose Medallion

This is a 12-inch (approx. 305mm) compass rose medallion designed specifically as a center inlay for tables, woodworking projects, or custom epoxy pours. Now available in a smaller 6-inch size.

The original model was used to level and restore an outdoor patio table featuring a sloped, sunburst wood-wedge design. By setting this medallion into the center and filling the sloped sections with tinted epoxy resin for a nice flat surface.

Printing

3D Printing Recommendations:                                                                                                                                                    Material: PETG, ASA, or ABS to ensure the model stays rigid and holds its shape during the epoxy's chemical curing cycle.

• Infill: 20%–30% (Grid or Gyroid).

• Top Layers: At least 4 or 5.

• Perimeters/Walls: 3–4 lines to ensure clean, crisp details on the raised rings and text.

• Orientation: Print flat on the build plate.

• Supports: Only required on the interlocking alignment joints (the sections with the extended pocket tabs).

File Options & Build Plate Compatibility:                                                                                                                                        To make this project accessible for all printer sizes, the files are provided in two formats:

• Full Medallion (1 Piece): Perfect for large-format printers (requires a build volume of at least 310mm x 310mm).

• Quadrant Sections (4 Pieces): Interlocking 90⁰ segments designed to fit easily on smaller printers (like 220mm or 256mm build plates). Simply print four sections and assemble them. Two section include alignment tabs and two include the corresponding tab pockets for a clean lock.

Assembly

Multi-Part Assembly Tips (For 12" Quadrants):                                                                                                                            If you are printing the quadrant files, use these steps to ensure a flawless center medallion before pouring your epoxy:

1. Clean the Seams: Lightly sand the joining edges of each quadrant to remove any elephant's foot or minor print imperfections to ensure a tight, seamless fit.

2. Bonding: Use a high-strength CA glue (superglue) or a 5-minute plastic-bonding epoxy to fuse the four quadrants together on a perfectly flat surface.

3. Fill the Seams: Apply a small amount of plastic filler along the top and side seams, then sand smooth to completely eliminate the join lines.

4. Seal the Back: Tape or seal the seams on the backside of the medallion before mounting it to the table to prevent any epoxy from bleeding through the cracks and creating bubbles.

Post-Processing & Epoxy Tips:

• Achieving the Metallic Look: To replicate the metallic bronze look shown in the cover photo, spray paint the assembled print with a metallic bronze, copper, or brass base coat. Once dry, brush a dark acrylic paint wash into the recesses and quickly wipe it off the raised surfaces to simulate an aged, authentic patina.

• Prevent Floating: Ensure the 3D print is fully adhered and sealed to the table center using silicone or epoxy. If it isn't completely secure, it will float to the top once you pour your deep-pour resin!

• Popping Bubbles: Pass a propane torch or heat gun lightly over the resin surface immediately after pouring. Pay close attention to the raised geometric points and lettering, as air likes to trap itself around sharp corners.
