For a freelance project, my client originally asked for a hard hat design. They didn't want it at full scale as you can see in the photo, they wanted a small, printed version. After seeing the final look, the client really liked it and decided they wanted to turn it into a keychain, so they asked for a quick revision.

My plan was to add a keychain hole at the back and place their logo on the front. To gain some hands-on experience modifying STL files directly, I opened the STL file and added both the hole and the brand logo right onto it.

By the way, saving modified STL files takes forever! If you can avoid it, I definitely don't recommend messing around with revisions on STL files 😄
