Post-Printing =============

Glue round rubber or foam sheets (optional)

You may want to glue 3 round 10 mm (0.4 inches) rubber or foam sheets with 2.5 mm thickness to the bottom holes of coin A and B. This will make the coaster sit on the table in a stable way.

How I Designed This ===================

Coin design

The coin was designed with Blender. I have designed the flat base coin first. Using a reference photo I have extruded points to match the text and ornaments on the top surface. Due to the inner and outer part this was quite complicated to design. I have used lots of booleans in Blender.

Inner top and bottom parts of coin A printed in a silver color.

Outer top and bottom parts of coin C printed in a golden color.
