Bird feeder with Voronoi pattern

If you like my designs, why not come and say hi on Instagram or Twitter!

Overview:
3D Printable Voronoi bird feeder for small birds. 
There are two slightly different versions so take a look at both and see which you prefer!
Pictured is the single-walled version.
The double-wall version takes considerably longer to print but has less extreme overhangs.

The insert is for if you want to use seeds/other food that is small enough to fall through the holes. It should be printed as a separate piece.

Print Settings: 
They're designed to be printable without supports. There are a lot of overhangs in both models though so you'll need good part cooling. Good retraction settings will be important too as the model is prone to stringing. Use a brim. Feel free to scale the models up or down. 
A variety of nozzle sizes and layer heights will work here.

They may take a long time to slice due to the complexity of the geometry and size of the files.

Other Info:
Designed using a combination of Solidworks and Meshmixer.
