I designed this model to swap out colours in layers.
As you can see I first started printing in a yellow/gold, then when the first 2 layers were done i swapped to red, then black and finally when the letters began white.
So this is a very good model for printers like mine, that can only print in one colour at a time and swap out filaments.
Just make sure you pay attention and don't get to distracted I did a lot of the time. :)
For me it took about 2h to print at an average speed, so if you do want to swap colours make sure you have the time to stay near your printer or check in regularly.
On the smaller version that I made, I was to late with the colour swap and just cut of the words from the model, printed them separate and glued them on.
