I made a bird feeder for wild birds using yakisugi (charred cedar) boards. Examples of its use are shown in the photos at the end. It can be easily attached and detached to your home's window glass with suction cups. Please attach it by slightly wetting the suction cup mounting surface. When removing it, you can easily remove it by inserting a thin object, such as a cutter, between the suction cup and the glass. The food container is detachable for easy cleaning, and I also made the same hole on the window side so you can easily see the birds from inside the room through the hole. The diameter of the hole is about 11cm, and a plastic plate is set, but you can also replace it with something else to your liking. (For reference) The load capacity per suction cup is 300g. ★ When shipped, it will be disassembled and packaged as shown in the photo, so please assemble it yourself. Since it has been disassembled once after assembly, you can easily reassemble it by aligning the three screws with the existing holes and tightening them a little at a time with a Phillips screwdriver, about 5mm each. ★ If you wish to have it shipped in an assembled state, the shipping cost will increase, so it will be 1500 yen, which is 550 yen more. ★ The suction cups will be attached at all four locations when shipped. To allow for suction cup replacement, they are each screwed in through the suction cup holes. The main dimensions after assembly are as follows: Height: Approximately 20cm Depth: Approximately 23cm Width: Approximately 14.5cm Hole diameter: Approximately 11cm This is the work of an amateur DIY enthusiast, so it is not perfect, but I made it as carefully as possible. I hope you will enjoy using it.
