Another take on a coaster

Just another take on a coaster.

I used the general size and shape of "The perfect coaster" to create this one.

The ridge is 1mm higher than the center. Grooves are 4mm deep by 2mm wide and top of the ridge is 5mm from the bottom. It can hold quite a bit of condensate before it fills up.

Overall dimensions are 80mm by 7mm.
