This is another of my series of Adventure Pug™ themed coasters, created with HueForge. This is designed at 4.07mm thickness and 100mm (4-in) square, but can be scaled up to make it into wall art.

Due to the thickness and 100% infill, make sure you have really good adhesion, and turn off the aux fan to minimize the chance of warping.

I've included 4 print profiles for convenience:
