I designed this blueberry picker to speed up my mission of eating every wild blueberry in Sweden. It works well and sure beats picking berries one by one!
All parts print without supports and should work out with your default printing settings, with the exception of the 'comb' part, which I printed solid using ABS for resiliance (I did also use ASA for the bottom, but I don't think that was necessary).
This worked great for me, but I have made a few slight changes to the models since my own print, which should make the parts stay together even better, but please comment if you run into any issues. I also added an alternative bottom with smaller holes, since I noticed the 7mm comb still plucked some smaller berries, so the 6mm Bottom might catch more of those precious berries!
