SummaryDesigned and printed this for a fellow biker buddy after he saw my BMW keychain I made http://www.thingiverse.com/make:223363 (see last photo) Multi colour achieved by manually pausing the print in Repetier Host at the appropriate layers and swapping filament as required because I didn't feel like hacking Gcode... :-) Would have liked to make it more authentic by printing it in Kawasaki neon Racing Green which I don't have.Print SettingsPrinter Brand: RepRapPrinter: Prusa i3Rafts: NoSupports: NoResolution: 0.2Infill: 30%Notes: I used different brands of PLA which have different optimal print temperatures. During the pause between layers I also changed the temperature to suit the filament and purged the nozzle until the previous colour was cleared. It goes without saying that you have to move the print head out the way when doing this so you don't mess up the print
