3DBenchy with a Christmas hat and an ornament hook.
Model is color swap compatible, no need for a fancy MMU or AMS.
This model does require supports (I know, I know), but its only a little bit for the hat, just put a little support enforcer there and turn on organic supports!
Printed at 0.2mm, 20% infill (settings don't matter, just print it how you print your normal benchy's)
