Another take on a coaster

thingiverse

I'm just messing around with a new coaster design. I based this one on "The perfect coaster" that's been floating around, but gave it my own spin. I tweaked the size and shape to make this one work better for me. The ridge is noticeably higher than the center, giving it some extra depth. The grooves are pretty deep - 4mm down, with a width of 2mm. That puts the top of the ridge at 5mm from the bottom, which should hold a decent amount of liquid before it's full. This design measures 80mm by 7mm overall, giving me enough room to make some adjustments if needed.
