Birb feeder

thingiverse

I'm using a bird feeder that's locked onto glass or any smooth surface using suction cups with a stem diameter of approximately 8 mm. The suction cups are held in place by two pins with a diameter of about 5 mm, and it worked perfectly for me. I got these suction cups when I ordered some screen repair kits from eBay a long time ago. You can also edit the .sldprt parts in Solidworks if you need to make any changes. I used Solidworks to create this bird feeder design. The bird feeder is made of Grey Creality PLA with 20% infill and no supports, and it was sliced using Prusa Slicer.
