Should be printed in PETG or another high melting point material, PLA will melt and warp at the temperatures inside a dishwasher. PETG is also on the more food safe side of filaments, so it's what I used. Definitely requires supports; with the geometry of the part there isn't really a way around that. It snaps into place and then rolls freely. I'd recommend either printing two at a time or doing some kind of pausing between layers because the part is small enough to cause blobbing in PETG. It will string a lot without being dialed in too.
