I made a bird feeder for wild birds using burnt cedar boards. Examples of use are shown in the last photo. It can be easily attached and detached to your home's window glass with suction cups. Please wet the suction cup mounting surface slightly before attaching. To remove it, you can easily detach it by inserting a thin object, such as a cutter, between the suction cup and the glass. The feeding 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 replace it with something else to your liking. (For reference) The load capacity per suction cup is 300g. ★ When shipping, 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 little by little with a Phillips screwdriver, about 5mm at a time. ★ If you wish to have it shipped assembled, the shipping cost will increase, so I would like to charge 1500 yen, which is 550 yen more. ★ The suction cups will be attached at all four locations when shipped. The suction cups are attached with screws through the suction cup holes so that they can be replaced. 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.
