Quick & easy- I made this in Google SketchUp in about 5 minutes (they have a 3D text tool), then converted file types and printed on a PP3DP 3D printer with ABS plastic.

I'm trying painting it to make it prettier- anyone have (better) suggestions for coloring extruded ABS plastic?
How detailed is the printing? Could you design in tiny grooves you could fill with something colourful? <br>
Actually, it comes with tiny grooves built in- the ABS plastic makes a ridged surface. <br />Painting with acrylic paint worked surprisingly well, though I'll be really impressed if it stays on- and the texture is kind of weird. <br />I was going to try enamel to smooth out the surface while coloring it, but there were lots of "keep away from heat" and "toxic" labels, so I thought perhaps not the best for a coaster..
Speaking of enamel, how about nail varnish? <br> <br>I saw on the shelves of a local store, there are varnishes now that make odd textures as they dry, and even one that makes patterns in the surface if you hold a magnet over it as it sets!
Very cool! I'll have to check it out. <br />For hot things, I'm still a bit concerned about toxicity, but I have some other 3D print things coming up...
