There are 2 versions, with or without front grill. You can download STL or STEP files. After import, dissasemble object, and apply colors to parts. Its 0,3 mm cut, so USE 0,3 mm FIRST LAYER. I used 60% size for keytag (in X/Y axis), resize yours according to your need. 

It is printable without multimaterial printer (tried on Ender 3). Only 2 filament changes (3 colors). Mine printed with ABS, but it does not matter.
