There is a gang of noisy sparrows who are friendly enough to share their own balcony with me - at least as long as I stay silent and don't move too much. They love to pick those white minerals that emanate from the outside of my terracotta planters, and wherever they can reach, it has been picked clean. Since they really seem to need that stuff, I thought how to give them access to those rich resources at the steep wall of the big planter, and this is why I created the thing. It is a fast print, designed in FreeCAD and the source is included so you can adapt it to your needs if you like. It is a tight fit for the halters - intended - and depending on the precision of your printer, you may need to widen the holes with a manual drill. But don't overdo it or you'll need a drop of superglue to fix them again.
