Honeycomb hollow riser

I was sick and tired of being unable to find a propper stand/riser after many bad experiences with other designs. 
I have uploaded my prototype and the model I designed using 3d builder. I'm assuming someone can make a more elegant solution where it can emboss by code, but in the meantime this will do.

For rising figures, print at 0% infill and 2 or 3 vertical walls. If you're going to be using this for a mat or something like that, I would recommend gyroid infill and PETG instead of PLA.
