I made this to be able to use my Bird Buddy in “anything”. There are three different versions here. One where you insert the BB from the back, one from the front and one “standing” (insert from the back). You need a 15x4mm (neodymium) magnet to insert in the holder. This is for the sensor in the BB to know it's in the holder. :)

You basically print the holder cut away the layers for the indent and magnet hole (it's made that way to be able to print without support), then mount it in to whatever you want. :)  

The standing one you see in the pictures, I just made that one to be able to see the birds (and other animals) bade and drink…  :)

I also use a separate solar-panel to load the BB-battery. 

Also, the SketchUp file is there too, if you want to make any changes. :)
