I decided to print a hat missing in my Santa Claus costume, however it came out without any geonodes hair???

The problem is that you need support for your hair, because the people who make 3D printers are lazy.

After printing, carefully cut away the support struts with a sharp knife.

If you don't have a sharp knife around, you can just print one!

Don't forget to mark edges as sharp where appropriate.

pretty stiff

3D printers don't support deformation yet. What you need to do is print out a lot of hats and then change your hat 24 times a second. It sounds tough, but like everything else, it gets easier with practice.
