@Silhavik No worries. I assumed you had designed it as one whole object and then split it up. I thought it might print nicer that way. But, it looks like that’s not how you modeled it. Thanks for replying.
@nirvdrum_71463 I'm modelling this in Blender, and it's often very difficult to split complicated shapes, so it's easier for me to model each part separately.
Downloaded the low version STL, and printed as expected in PETG on my MK3S. Appreciate the clean, support free design with no overhangs. Using this to add feed to small cup birdfeeders. Thanks!
