We all have that favorite hoodie, now we can use it to hold stuff on our desk! The strings are printed separate from the rest of the hoodie to allow you to position them in just the right location.
You will need supports. I recommend using a support blocker to keep the supports just on the sleeves. Also, I have found that it is best to print the strings flat with supports (for FDM).
