This is a hex leg riser for Wyrmwood's hex table. 

Add 54mm or 2-1/8" to the table height

The table vault made the clearance a little too small for the new stools I bought and needed a little extra space to fit legs comfortably under the table. I've currently got six on the table printed with default infill (~15%). I expected them to break immediately, but it has been about 3 weeks and they are still holding strong without any deforming. Should they break I will be printing again with higher infill.
