This is another entry for the Coasters design contest. 

The Coaster is ‘industry standard’ size of approximately 100mm x 100mm. I created a design from one of my favorite toys as a small child - the SpiroGraph.

I designed the coaster with lots of walls to avoid infill between the lines.

The Coaster Holder is designed to hold four coasters. 

This model was created using TinkerCad

Recommended Print settings:

• .30 mm layer height
• 5 perimeters
• 30% infill (for solid feel and smooth top layers)
• 4 top and bottom layers
