Not Alone Insert - Remix

List of changes :
- increased dimensions for sleeved cards (mine are Ultra pro 66 x 91) :
- Original : 66 x 91 (x3)
- Remix : 67.25 x 94 (x2) + 68 x 94
- increased bottom thickness (robustness / easy printing)
- Original : 1mm
- Remix : 1.25mm
- Red cube tray arrangement (dunno why but I have an extra cube in my box)
- Original : Last layer of cubes can't be grabbed
- Remix : 2 cubes at one side are lower by half a cube height
