The model I remixed this from had a weird notch at the bottom, didn't feature any numbers and the hole to put a cord through was kinda too small for me.

That doesn't mean, that the OC didn't do a great job at designing a good baseline. But I made the changes I deemed necessary and thus these three medal models came to be.
Feel free to print them in any colour you'd like but I can recommend you print them in gold, silver and bronze(/copper) respectively.
