Did you need supports for these?
No supports at all - I used the version where you have to glue the handle pieces together, instead of the all-in-one handle print. Also, I fill them with dried chipotle flakes and give them as gifts.
Thanks! This design is terrific, excellent work. I just happened to have about a hundred of the 6mm rare earth magnets that fit the holes exactly, so I'm going to keep printing these and giving them to friends until I run out.
