Note that the model is not sized to be a direct C64 badge replacement. Scaling down to the correct size may be a challenge to print, but not sure yet.
If you don't have an AMS or multi-material printer, this can be printed using the method outlined in a video on the CHEP YouTube channel found here. This method easy once you understand it and work out the details. It also results in a very nice surface. The general idea is to print each model separately, but leave them on the bed. With z hop / raise z enabled on retraction, the nozzle is lifted to clear the previous extrusions. I set the color bands and text height to 0.4mm with 0.2mm layers height, so my z hop / raise z was set to 0.5mm.
