This is a more advanced version of a hanging bird feeder I made 2 years ago. Since it was quite famous, I decided to make this one and improve several things like:
- the design was so edgy. I use my implementation of bezier curves for some fluent curves
- improve the roof mount to add more stability
- make it fully customizable (it is in OpenSCAD, just download the source or use the thingiverse editor to customize it as you want)
I configured a small version (for small 3D-printer) and a big version (for 330mmx330mm 3D printers).
