New to printing

[apple_user_1772460510]

Hi all. I am an absolute novice when it comes to 3d printing. I’ve recently purchased the TINA2s for my son and really don’t know where to start. He is looking to print little things such as mini figures, key rings and fidget toys to start with. The library on this app isn’t great. Where do I find better things and how would I use it. Thanks in advance.
