Six Gallon Can Lid Adapter to Platform Bird Feeder

A House Finch suffering from Finch Eye Disease prompted me to sterilize our feeder, which meant providing a temporary feeder to keep the birds flying. Having an abundance of lids from six gallon plastic cans / buckets, this made sense:

Which required an adapter betwixt pole and lid:

Which requires a bit of solid modeling:

The lids have a central boss, presumably for stiffening, so the model includes a suitable recess:

As usual, automatically generated support fills the entire recess, so I designed a minimal support structure into the model and cracked it out with very little effort:

The tangle off to the right comes from a bridge layer with a hole in the middle, which never works well even with support:

Can Lid Platform Feeder Mount - Slic3r - bridge layer

Didn’t bother the birds in the least, though, so it’s all good.

I loves me my 3D printer …
