Good to see my design/measurements getting reused!
Please be aware of that the measurements were done of my own Axoloti board. I've noticed that someone had a slight offset on some port(/s?). So he had to file his panel a bit. Best option is to print it out (from the FPD freeware = front panel design software) on paper, cut out the holes with a small knife. Try with the paper on your own board. Then you should notice any differencies. Adjust (on your copy of the FPD file) and repeat. Please note that you can set your own grid resolution in your FPD for very precise adjustments (I think I had mine on 0,25mm).
Hope it all works out for you and good luck! And if you don't mind, please share an image on that thread you linked! IMHO, it's inspiring to see everyones version/solution.
