How do I add a 4mm hole for a keyring in the top of this Suzuki logo? I am a beginner and have tried everything I can think of.
Do you have any solutions?

STL files cannot be edited however you can do simple booleans such as punching a hole.
Like this…

For what it’s worth, here’s another approach. Add a keyring loop on top of the logo. Once you do a **Union** , the loop becomes part of the STL file.
