Coin coaster Namibia 50c

Realistic Namibia 50c coin as a coaster

This is a replica of a Namibia 50c 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.

You can use any filament color which you like for the Namibia 50c coaster. The original color of the 50c coin is a light silver.

If you do not want to glue rubber into the coin, please use the model "Namibia_50c_no_holes_01.stl".

Post-Printing

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.
