This is an slight upgrade of previous remix, adding at the beck side treated holes for screws and labels.
I used a filament changes one layer too early, so the final print was in three colours, but using 0.2 resolution change finalement at layer 51 and only numbers will be in different colour.
Actually, I like this three colours combination ;)

change colour at layer 51 (using 0.2 resolution)
I also use infill 2 lines to make a print faster and strong as 20% or more (with only 10% infill)

treated holes are so small from M3 that a little cleaning (treating) the smaller holes may be required
