Update: it has been completed 3/16/2017
So I have only owned my switch for 10 days but I am already going to tattoo the back of it. As of now I have the boundary area where the laser can go without damaging the logo or anything else.
As for the design, I am pretty much set on some sort of Splatoon design but I just have to do a whole bunch of photochopping to see what will look good. If all goes well, I will probably have it all set on Thursday.
Oh, and if anyone wants a DXF or a Corel Draw template of the boundary area just leave A comment and Il put the most up to date one on Thingiverse. (for the NA version, looks like other regions have slightly different marking layouts so the design may overlap)
