I found K2_Kevin's Pencil, Pen, Marker Holder for Honeycomb Hex Wall. I liked it but I didn't want my pens falling over (I'm like that, don't judge me ROFL). So made it solid and put in some hex channels to put the pens in.
It came together well, but I don't like how the design worked in Freecad, so no freecad file. But I did add the .step file.
Hope you like!
