If you travel into the State of Colorado, from any surrounding State, you will likely encounter one of these signs. They are built, erected, and maintained by the Colorado Department of Transportation and have been welcoming visitors for years.
The first thing my son asked me to produce when we bought our 3D printer was this sign. It's not extremely refined and might benefit from someone with more 3D printing experience than me, but I present this model if you want a desk sign or refrigerator magnet to commemorate your visit.
The author marked this model as their own original creation.
