This is a remix of srmalloy's hex tile. It's shorter, which allows it to print faster and with less material, while still being tall enough to allow a noticeable height difference when stacked. I've also shortened the connectors so they do not show when they are interlocked.

I've included 2 versions of the model, which are identical other than one of them being flipped 180 degrees (printing the top of the tile on the bottom). This version prints with fewer supports.
