MMU2s fun models

Hi all!

I hope everyone had a Merry Christmas. After a long wait, I finally received my MMU2s kit on Sunday. I'm pleased to report that it is assembled and working great. Does anyone have models they printed with theirs that are particularly cool? I plan on making my own as time goes on for Nerf blasters (as I am the Nerfdoctor), but just looking to have some fun for now. Thanks!
