I whipped this up while the full height version is printing. 8mm seems way too high for the honeycomb part of the coaster, so this is 3mm in height. The print time on the 8mm version was estimated at around 4-5 hrs with a 200 micron layer height. mind you this is with flexible PLA so the speed is quite low. At any rate this will print much much faster and should still be a great coaster.
