I looked through all the models of tray inserts and found one that I could easily modify to suit my needs. I added nozzle storage compartment and a place for nozzle cleaning needles.
The uploaded version is improved, the one I have printed had too small tolerance for nozzle diameter and they would barely fit, it also has larger text (nozzle diameters). 
The tiny divider at the bottom-left corner is perfect for storing spare blade edges for the HexScraper! https://www.printables.com/model/278652-hexscraper-blade-swap-mod


According to the comments the improved file works perfectly, you can print it with any material that you have, supports are essential and low infill should be good enough
