Just took the 18650 hex model and scaled it up to work on my 21700 cells. I'll also include the scad file so you can take the files and make any custom size pack. I included a single up to 4 side by side. I just split the 84 cells into 2 pieces though to easily fit my print bed.
I'm still waiting for terminal insulation rings before soldering in the nickel strips.
