Bird fat ball feeder

prusaprinters

<p>A simple bird fat ball feeder. It prevents the feed from getting wet and makes it easier to swap fat balls once they are eaten.</p><p>Just add a piece of string with some knots in it in the hole and tie it to a branch. The hole becomes smaller towards the top, so the knots will catch it.</p><p>It contains a little hook where you can attach the fat ball onto.</p><p>I print these in PETG without any supports.</p>
