Realistic penny coin as a coaster
This is a replica of an Australian Penny coin for use as a coaster. The diameter is 10.1 cm (3.9 inches). The back side is flat with 3 round insets with 10 mm (0.4 inches) diameter each. You can glue some rubber into the insets to make the coaster sit on the table in a stable way. However, the coasters of course also work without the rubber support.
The Australian coins "One penny" were minted between 1911 and 1936.
You can use any filament color which you like for the Penny coaster. The original color of the used Penny coin is a dark brown. The original unused Penny coins had a copper color which I have used for the photos.
If you do not want to glue rubber into the Penny coin, please use the model "Penny_coin_no_holes_01.stl".

For Cura slicer you can set the "Infill" -> "Minimum Infill Area" to 4000.0 mm2 to create a clean coin base without strange infill spots for the top letters.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. 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.
