Make your own coaster!
Step 1: Step 1: Making the Base
Depending on what types of beverages you are going to set on the coaster, make the diameter according to what you see fit. Do not forget to make a larger circle on the outside by using the offset command in autocad.
Step 2: Step 2: Design
If you wish to make a design go for it. In this case I simply just made a star in the middle to add an unique trait to my coaster
Step 3: Step 3: the Width
In this case I have made two circles. The bigger circle on the outside will be raised higher than the one in the middle because that way, no liquid can spill outside of the coaster. Also I purposely did not raise the whole middle, instead I only raised everything but the 5 points of the star.
In this example, I raised the outside circle by 0.5" and the rest by 0.2"
Step 4: Step 4: Add Color
When you are done with all the design work, feel free to add some colors to make everything pop!
