I mode it using bambu studio to have Nemo face both side but takes lots of effort to do. it would be better if you can revision to have both side since keychain spin around.
Hello. When i started doing keychains, a got a lot of comments about making the Back of the keychain solid color, so after that i made all with a solid color on the Back. I will update some with having the same on the Back as the front, but it takes much more filament becouse of the more color changes.
