I used PLA material with a granite motif for printing. I adjusted horse back where the mane ends. I also added a tail from another project. He removed the horse fur and added his own version. The original model had a lot of problems with printing. I recommend printing at a scale of 175%. On this scale, the pony can already be seen via the mobile phone, which my daughter claimed.
