Summary This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/829qIEL3kno I used this coaster by wilson05, published Jun 18, 2017 you can get it here https://www.thingiverse.com/thing:2392168 if your not wanting to color the viking and save the time it takes to do it my way( I have nothing but time these days so it works for me L.O.L. Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: No Resolution: 0.2 Infill: 20% coaster 100% viking Notes: after printed color the viking press it into the coaster clear coat the viking being careful not to get clear on coaster(you can clear viking before then just apply a good amount of clear on edges once it is placed in coaster) To seal any openings or condensation from a cold item sweating on warm days might leak and get surface wet which will defeat the whole reason you are using a coaster in the first place i plan on using a felt material on bottoms that will protect the surface it sits on as well as cover any light that shines thru(yes it has a coat of clear coat to seal the part but it is clear so light comes thru as you can see in the pic. HAPPY PRINTING!!!
