Birb feeder

Bird feeder. Locked to glass/anything smooth using suction cups with a stem diameter of cca 8 mms. Suction cups are held in place with a set of 2 pins with a diameter of cca 5 mms. Worked like charm for me. I got these suction cups while ordering some screen repair kits from eBay long time ago.
Including .sldprt parts, feel free to edit them in Solidworks, which I used to create this.
Grey Crealitya PLA, 20% infill, no supports. Sliced with Prusa Slicer.
