Large birdseed feeder

A workmate has quite a  few budgies in different aviary cages and wanted something simple for feeding that could re-use common jars.  

This feeder fits the large coffee jars available (well, in NZ anyway) with a 62mm mouth (or 88mm incl thread).

Need supports under the perch, but ok elsewhere, and I found 3 perimeters and 8% infill resulted in a lightweight but sturdy print.

After in-field usage, feedback indicated it needed a little more thickness - updated.
