cartoon trumpet 3D model

I didn't realize that this file is in Cinema 4D .c4d format. I thought it was a .obj because that is what I was searching for. I have no way to convert it so It's my fault for not pre-checking the file format. If there is a way for the author xiaoyima to convert it that would be great. But since it looks like they may be from Japan I hope they can translate this.
