Got my new full size keyboard briefcase from Massdrop, fits my Ducky YOTG nicely

That case is sweet! I wonder if it would have fit a Model M?
Probably not because Model Ms I believe are too wide.
These are the dimensions of the keyboard briefcase from Massdrop if you want to compare and see:
Interior dimensions, approx: 42 x 13 x 2.7 cm (main compartment only)
Exterior dimensions, approx: 46.8 x 26 x 6.7 cm
