A coaster that goes where ever the drink goes! I was modeling a koozie and found I liked the coaster version the best. Best to print in a flexible filament as it's a snug fit. See it here The coaster koozie has a smaller diameter than the short and tall versions.
I create these designs to encourage people to try out flexible filaments or get some new interesting colors of flexibles. For info on purchasing samples of several brands of flexible filament, TPU for as little as $1.99 per sample (free shipping) goto 3dprintny.com
