Would recommend adding a brim and supports on the handle because of the fast bed movements! there is a slight overhang in the ring, which works fine on corexy machines but the bad slingers might tip the prints over! :)
I printed a pair of these for my 10yo son - he loves Naruto and was designing something similar in tinkercad before he found this model. it's a great model. gluing together required a small rotational pressure to make a strong bond between the peg and handle/knife, which was nice and easy to build once we decided to add that twist while the glue was drying.
the point is pointier than i expected! perhaps i should have modified before giving to a young kid...
