Made this as a gift for a friend of mine who is wheelchair bound. Something to put on the back of it when he goes out so people don't try to rush him.
I printed this in PLA in 2 colors. The yellow for the base and did a filament change to black at layer 12 for the second color.
Did a filament change for second colour. Use Pause at Height/Layer in Cura to set the change. I changed at layer 12 if printing at .2mm layer height.
The first one I did, I set it to repeat last layer and it made a mess. I'd advise against that if your printer is dialed in. Just do regular pause and change filament and go.
