Briiiiinnnnnng. For the Yip Yips, there are 2 files, one for the main body and one for the antennas. You can size it up or down. May need a little coaxing into the slots. I usually print the antenna on a raft with supports if making it small. Body can print in place with no supports. Yuuuuup yuuuup yup yup yup.
