A few days ago I needed an eye patch and thanks to CptPicard and his model (https://www.thingiverse.com/thing:3119188) I was able to get a patch. The reason why I'm posting this is that I modified the file to be able to print it in a different direction because I didn't want to sand it so much.
Therefore, here you have the same file ready to print upward. Also, you will see that I created a back structure to make it stiffer, it isn't necessary (because I printed the one I was wearing without that structure) but the surface quality with that support is better especially for the model with the Jurassic Park logo.
The model is sized for an adult, but if you want to print it for a kid, I recommend you to print it at 80-90% scale.
I hope you like the Jurassic Park model; my nephew is going to love it.
If you print the Jurassic Park model use a 0.25 nozzle, the quality is much better. But you can print all of them using a 0.4 nozzle
Just break the back structure and the base with your hands and sand the tiny spots that will be left.
