Floating drink coaster to annoy mom

So...was playing around with Sketchup, learning how to get the follow-me function to work nicely and made this. Quickly, remembered how my mother HATED coaster that would skitter around on a table when the condensation would make them float. Thus, I optimized this to float quite a bit.

Now, these are placed in strategic locations all around the house, just for mom.

When you print this, use a pretty hollow infill to maximize the effect.

For all the mom's everywhere!
