How to Customize

If you would like to customize, download coaster template, and go to: https://www.tinkercad.com/dashboard. Create an account/login and start a new project. Click the import button in the top right, and import the coaster template. You can now make your own design, or convert an image as shown below.

How to convert image to stl

Download the image or simply click and drag it into https://imagetostl.com/. I would recommend using black and white clip art photo because those will show up best on the coaster. Ensure that there are no watermarks on the photo. Click Invert output to ensure that the black is the part that is modeled. After you have gotten a design you are happy with, click the arrow next to download, and click download as stl. Go back to Tinkercad and import your file. Adjust and resize as needed.

How to get multiple colors

To get multiple colors is very simple, even if you have a single extruder like me ( I have the Neptune 3 pro). You simply have to switch out filament colors part way through. Be careful that the printer is finished the back ground and started the design, or you will not get the contrast in colors.
